Overall, this is a strong textbook and has many positive attributes.

If the corrections to Unit 1 were made and the text included a more racially and gender-balanced focus, then it would be superior to traditional textbooks. One final note: the addition of review questions at the end of each module are great, in theory, but almost all of the multiple choice questions require only simple recall from students. Including questions higher up on Bloom's taxonomy would demonstrate to students that they are expected to synthesize, apply, and otherwise critically think about the material.

The book covers a wide range of content appropriate to a non-majors level biology course or survey introduction; with the exception of a few content areas such as evolution and diversity of non living and lower organisms, Plant diversity and The book covers a wide range of content appropriate to a non-majors level biology course or survey introduction; with the exception of a few content areas such as evolution and diversity of non living and lower organisms, Plant diversity and physiology, and the mammalian sensory system.

For example, the 3 individual chapters covering Non-living organisms and prokaryotes together, Protists, and Fungi in our previous textbook were consolidated into one massive chapter. The same occurred with the plant content. The 5 senses were completely glanced over in the segment off Body systems. On one hand students appreciated have "less" reading outside of class, however, the lack of additional coverage in the textbook may have been a contributing factor to student success in the first year of adoption.

Even with the utilization of the same lecture materials pre and post OER adoption and the same exams being proctored. Students who used the text were under-prepared for the assessments. One could argue depth required in subject matter, specifically in introductory courses, however, across the department, we felt the lack of coverage in these areas was a disservice to our students. Even though we may have covered the content in lecture, they needed to have additional exposure to the content outside of class to increase their retention of the material.

Our fix: We remixed and revised the Openstax Concepts of Biology textbook with chapters from the Majors "Biology" text that were trimmed down, removing concepts we thought were beyond the reasonable limits of an introductory course.

Utility navigation

In the following year, the student success "bounced back" and became comparable to the pre-OER distribution of success. Content is accurate, error-free and unbiased. It is also clearly worded to aid in student understanding. With the exception of Chapter 10 on Biotechnology the content is up to date and worded to focus on the models of previous scientific processes and the "big picture" generalizations, which will aid in the longevity of the text.

As far as Biotechnology goes, that field is rapidly growing due to the advancements in the field, and I could see needing to supplement a paragraph or two within the next 5 years. Text is clearly worded, concepts are focused on major distinctions and terminology is added in a progressive pace, making it easy for students to build upon.

There are also ample examples of concepts which can provide context for student understanding. The pace and focus of the material is consistent throughout subject matter, this provides student with a regular framework in which to access the material. Having used this text in a Revise and Remix model, I can attest to the modularity and ease with which we were able to supplement content in a course and even term specific manner.

The chapters progress on content appropriately, which enables our year long sequence over the span of 3 courses to generally proceed in a linear fashion; with the exception of Unit 6 Ecology being discussed following the unit 4 coverage of plants and plant dynamics. The books interface and navigation has been seamless for a majority of my interactions. The text is written scientifically, without bias, and as a result has no culturally insensitive references. Even then, it is matter of fact and tastefully focused on the concept of immunity.

We have used this text across the entire Biology department for 3 years now, and both students and faculty are happy with it. It is a valuable resource in content matter, accessibility and scale-ability. This book covers most topics addressed in non-major level biology survey courses.

Therefore, I must use the level Therefore, I must use the level version of this text, Openstax Biology for that course. That is unfortunate because much of the Biology textbook is too detailed and technical for a non-major week course. Nevertheless, this book provides clear and accessible text on the subject areas that it covers. Each chapter provides a glossary of key terms and a few review and critical thinking questions. One significant drawback to this book is that wide-ranging and sometimes disparate topics are groups together into a single chapter.

However, some topics probably should not have been broached in this textbook. In sections Yet, neither of the descriptions of these complex processes are supported by images. If it deemed that these processes are too complex for non-major biology courses, then students would be better served by not having the topics covered at all than trying to puzzle out how depolarization works or how sarcomeres shorten in skeletal muscles without an illustration. There is a video embedded within this section that does describe the process but very few students utilize these links.

Fortunately, the immune system is given its own chapter in this book and provides a good basic overview of the components. I have not encountered serious issues in the accuracy or bias of topics that I cover. The brevity makes some topics difficult to understand. Broken links are probably the most significant accuracy issues comes from the extensive use of links to outside learning resources.

Even those that point to resources located on the Openstax site sometimes do not work or are not supported. However, the website has a good Errata section that you can submit errors and broken links to. These appeared to be addressed relatively quickly and editors provide a table in which the status of the reported errors or broken link is available. I have checked this table when I find a link that does not work to see if it has been reported.

As an instructor of non-major biology classes, I am particularly concerned with the take-home messages that students will carry with them long after they leave my classroom. This textbook provides many good examples of concepts and processes that are relevant to non-major biology students. The section on Genetic Engineering Chapter 10, Bioengineering provides a section on the application of genetic engineering and GMOs, a topic that students have many misconceptions about.

Some updates are needed; for example, there is a brief overview of the one-child policy in China, which needs to be updated. The paragraph in the book can be a good introduction that encourages discussion on why this policy changed. However, the brevity of the text means that a lot of concepts are introduced but not explained enough for students to understand their relevance. For example, the process and consequences of eutrophication and ocean acidification could be expanded, and while I believe that my role is fleshing out these topics is critical, these topics are so important and relevant that they should get better coverage in the textbook.

Ocean acidification is not covered in Chapter 21, Conservation and Biodiversity under the heading of Climate Change. One of the chief strengths of this book is that is editable so can be easily updated. The downside is that it is not clear to students who purchase used versions of the hard copy that changes have been made. The Openstax website provides excellent documentation of changes that have been made to the textbook, but instructors must help students understand how this textbook works so that students are not frustrated.

I use a hard copy that is a few years old so I am careful to consult the online version and update my PDF versions on a regular basis. The clarity of the prose is excellent and is written at a level that is appropriate for lower-division undergraduate students. It is very difficult to explain complex terms and concepts to a non-major audience and many of these students do not have strong reading comprehension skills. As I noted above in the Comprehensiveness section, adding a few more illustrations that support the text would be useful.

This book had many contributors, but it is consistent in both layout and prose. That is important because we cover most of the chapters in this book in our non-majors biology series. Importantly, formatting is consistent throughout the book in all versions. The modularity of this books works well for me because it is easy to assign reading by sections. The sections can be read in isolation but it is easy to assign one section in another chapter that will provide context. It is important that if you prefer using a hard copy of the book that you assign reading by section rather than by page number, which has no meaning to online readers and may be incorrect for students whose print version came out later or earlier than your version.

Because we organize our biology series in the same way, this organization works well. The interface of the book works well and I understood how to navigate the online version quickly. Some students have a difficult time negotiating the online version of the book. About half of the students in my classes who do not fully use the book point to their difficulty navigating it. This apparently is because each section e. This should not be a problem as it is easy to move to the previous or next sections by clicking on the navigation buttons.

The search function works well with the caveat that you need to hit the enter button to execute the search. Partial words or phrases are fine as long as they are not misspelled. These are the kinds of tips that students need to understand to fully utilize the book. It is worth the time to show students how to navigate the book rather than assume that they will figure it out.

Some of the images are not crisp enough in the hard copy of the book but they are readable. The photos are generally good quality and informative. The text is well-written and generally error-free. Any errors are easily reportable to the Openstax website. I have not found evidence of culturally insensitive or offensive material in this book.

I would recommend that the book use more examples that help students understand and appreciate the biological significance of the diversity of human traits e. I have used this textbook or the Openstax Biology textbook for several terms. I like these books and students are grateful for access to a free textbook. However, we need to understand how students are using these textbooks - or in many cases, not using them. In classes where I have surveyed textbook utilization, between a third and a half of students do not use the textbook or use it very little.

A few have technical issues and cannot access the book with older computers. This issue appears easily rectified by providing a hard copy of the textbook for a nominal cost, which Openstax has done admirably. We stock this textbook in the college bookstore to make it as accessible as possible.

I also require the use the online Sapling Learning support system to encourage students to engage with the textbook. The problem is that the siren song of free means that most students will not purchase the textbook if they can access it for free, even if they are unwilling or unable to read an onscreen version. There is only so much that we can do in this situation but it is important for students and instructors alike to be aware of it. I was an enthusiastic adopter of this technology and it was not until I surveyed the students that I understood the extent of this problem.

Much of the value of this textbook is virtually ignored by most students, particularly the embedded links to supporting resources. Almost none of my students access these links, even when I tell them how useful they will be to illustrate difficult concepts. In fact, many students automatically google for information much of it incorrect or incomplete rather than use their textbook. If we want students to use these resources, we need to be very clear that 1 the textbook is an important learning resource, and 2 they are accountable for learning the material.

We need to make hard copies available in college bookstores and on reserve at the library. We also must take the time in class to demonstrate how to fully utilize the features of the book. As instructors who were not immersed in technology in our formative years, we often assume that our students are more technically savvy than they are.

Most importantly, we need to help students recognize the kind of learners they are so they can use strategies that increase their engagement with these resources and their success in our classes. This text covers most ideas, however not always fully. Already, within the first 6 chapters, I have noticed many small, yet still important concepts that are not discussed. For instance: Hydrolysis and dehydration reactions are not discussed. The wording is used in a few places, but there is no defining section describing water's role in chemical bonds, which is relevant in many further concepts in the book.

These are crucial concepts necessary to the understanding of following concepts. It is understood that this is a book for non-majors, however, this is not quite comprehensive enough for a college-level non-majors biology course. I am pleased to see a glossary of terms after each chapter. This is very useful for students.

I have not noticed any errors, or blatantly incorrect information. The only small inaccuracy I found is that electrolyes dissolve in water. Salts dissolve in water, releasing electrolytes ions. These do not further dissolve. This textbook is basic enough that the information can remain relevant for many years. Most of this information is general concepts which haven't changed, nor are likely to change for many years. I think the clarity is great. It stays easy to read and comprehend for a non-majors level.

The context they are used in is not enough to derive an understanding of the words. I have noticed no issues in terms of consistency and framework. There is a nice flow to the information. All chapters are well divided into small concept chunks with appropriate subheadings. This makes it easy to direct students to what to read, verses what can be skipped, as well as allowing students to properly chunk notes taken from reading. On the computers and devises I have used, I have noted no problems with interface.

I know that my students are viewing the text in many forms, including tablets and smartphones, from which I have heard of no problems. I feel that there are many references and examples to biological situations, none of which I have noted any insensitivity or offensiveness. Most don't lend themselves to inclusiveness issues. Overall the book is well-done, and a blessing to be able to provide to students for free. I feel it just needs a bit more information added to it to round it out fully, and make it appropriate for a college level biology course.

I was motivated to search for an open-access text for my non-majors class in fall for two reasons. Second, textbooks in all of the Second, textbooks in all of the classes I teach are really recommended supplements to the other materials I make available, not required reading.

This text is quite exhaustive in coverage a stronger word than comprehensive — no major areas of the subject are omitted. This means it contains too much material for a single-semester course. In addition, I think it covers the majority of topics in more depth than is needed for non-majors. These comments need to be put in context. Almost all non-majors texts available in print also include too much breadth and depth. The upside to providing lots of breadth and depth is that the instructor has a lot of material to choose from.

Of course, it is the job of the instructor to guide students to achieving an appropriate level of understanding. And so, for example, the basics of transcription and translation will be the same next year as they are this year. However, Chapter Ten on biotechnology, will need revision and updating, whether by the authors or instructor. One simple strategy to underscore relevance is to include material from newspapers and other reliable!

It is crucial to show non-majors that biology is important to them and to society, and that it moves forward on a truly daily basis. Biology has its own vocabulary and technical terminology. This can sometimes lead to confusion — my favorite example is use of the concept of a theory.

The text certainly uses the language of biology, and does so in an appropriate fashion. Glossaries of terms are included, although I cannot find an index. In addition to diagrams, which are well constructed, there are questions that require some critical and synthetic thought scattered through the text.

The book includes chapter summaries and sample questions multiple choice and short answer, the latter called Free Response. These questions are not as numerous as in most of the print books I am familiar with. The text is organized into six units within which there are multiple chapters.

That said, it does prepare the student for detailed treatments of cellular respiration and photosynthesis to come — if the instructor deems such detailed treatments to be appropriate. The ordering of the Units, and that of chapters within units, does not follow the order I use in my class. For example, I deal with evolution in the first two weeks of the semester, as I believe it to be the lens through which all of biology should be viewed.

However, Units and Chapters can be organized in a way that preserves flow and connectedness as per an instructor's requirements. There are many stories that can be told about biology, and no one story is necessarily better than any other. The text tells a story that is different from mine, and so the organization of my class and the text do not match. The text is easy to use, and includes clear and relevant artwork and video clips.

Specific chapters are easily accessible through the Contents function - an index would be nice I can't find one. Additional on-line resources are available to the instructor, including but not limited to test questions and PowerPoint slides I choose not to use these, but they are just fine. I believe that Concepts of Biology is an excellent text for a non-majors biology class. It is accessible, nicely up-to-date, and covers relevant topics.

And, of course, it is free unless one chooses to make a donation. I provided students in my class with a survey to determine their opinions of the book. This is a disappointingly low number. I am pleased by this level of initiative. I asked about whether the book should be used again. Most students gave replies that I expected, for the most part. The book was judged to be useful and well-connected with my lectures, although more detailed. The majority view was that the text should be recommended in the future, a position with which I agree.

The book has a very easily accessible and complete table of contents. The online book works well in that each chapter title can be clicked on to open a list of the subtitles explaining the topics covered in the sections. The information covered The information covered in the book is well laid out and covers the all material that should be included in a level biology class. The material in the book is relevant to anyone who is alive and curious. The way the book accesses internet information is commendable- making it a very desirable addition to any contemporary students collection.

Updates to links may be an issue as time passes, and inclusion of varying emergent technologies or careers. However, that last part has always been true of science materials. I find the lay out impeccable. It introduces what it is going to talk about then talks about the introduced topics clearly with great graphic support. The fluidity of the writing is rarely found at this level.

The vocabulary appendices at the end of each Chapter make it friendly to all students including ELA. The pattern of Chapter, subtopic, vocabulary, review and questions is consistent and reliable. A great way for new"ish" students to get used to college level reading. For the most part, the text is divided nicely with graphics and career information or internet connections. There were a few areas with large blocks of text, but not many.

The dividing graphics and career information are not disruptive because they highlight subjects that are mentioned in the text. The organizational structure of the book follows a common flow of Biology texts. Those usually help a student comprehend the way the genes separate and recombine during reproduction, thus make for the genetic variances taught. But, besides that, the flow was perfect.

I noticed no interface issues. The internet book worked perfectly and every movie, link and picture worked well. No visible distortions. I noticed two areas where the sentences didn't flow well. One was written poorly, but that is not bad percentage wise, compared to the whole book. The text is not culturally insensitive or offensive in any way. Biology is universal and doesn't make reference to any particular cultures except for bacterial cultures, and as science is based on fact, there are no ill placed opinions about said bacteria.

Just perhaps a few less than positive hypotheses. I am thrilled about the availability of such a high quality and timely resource for lower level biology students. It is engaging where sometimes the science can get dry, and relevant for the students because of its direct tie-ins to careers. This text is used for non-majors Biology and I have used it as a textbook replacement for 3 years. It provides a clear and concise survey for the intended audience.

The table of contents allows you to view the sequential topics in each section. The Careers in Action is a real-world application of science for non-majors; this provides them a glimpse into the field of science. Each of the other sections are reinforcement tools for the students after their readings. The Free Response is also a great prompt for class discussions and discussion boards. In some areas, more detail can be added Chapter Body Systems. Text is clear and easy to follow for students and faculty.

The end of chapter glossary is there to provide clarity of technical terms. The text is easy to read whether the PDF, online or enhanced tablet version. The choice of device does not present any issues to the reader. The topics are presented in a logical, clear fashion which is similar to the organization of the course I teach. In the Chapter 16, there could be a bit more information on the Body's Systems; currently, I supplement the areas with other resources. There are not any interface issues I am aware of for myself or my students.

I have used the PDF as well as the enhanced version on a tablet and no issues. This has been a great resource for students at my institution by providing the content needed to successfully exit their General Biology course requirement. For some being able to print from the PDF or have it accessible to them on their mobile devices or even order a bound-printed copy relives varied levels of stress for them. Overall, I found this textbook covers the basic topics and concepts you can find in a classic biology textbook; it also provides information from recent publications pertaining to biomedicine and climate issues which can be interesting to Overall, I found this textbook covers the basic topics and concepts you can find in a classic biology textbook; it also provides information from recent publications pertaining to biomedicine and climate issues which can be interesting to non-major students.

I am planning to use this book next semester, and I think it will be a good textbook for me to outline my lectures, and for students to read relevant chapters before they come to lectures. The online version is especially handy because of the search function, as well as the links to outside information sources. The links to some hand-on modules seem very interesting and will be easily used to develop assignment questions.

This is true for other non-major biology textbooks not open access. I found the textbook to be accurate on the major concepts and current development in many fields of biology. There are many controversial issues in biology that different instructors might find they do not agree with the information provided by this textbook especially those sections to do with taxonomy and phylogeny , but I did not find major conflicts. I do have several minor issues after reading Unit 4,5,6 : Section I guess it depends on whether the authors consider Domain as the lowest or the highest level of taxonomy.

I always consider Domain as the highest level and therefore each group at one of the levels includes groups at the next highest level.

English Dictionaries

I found this paragraph a little confusing. Section Information in this textbook stays relatively up-to-date. Although there are a few places where I think the authors should have provided references for the readers to know where the information is from and how recent the sources are. For example, in chapter Since the phylogeny and classification of Protista is a very controversial topic as the textbook also mentioned , it is important for the readers to know where and when this classification system was developed, and whether there are alternative systems use as most other textbooks are using a system with five Supergroups.

Another similar example is in chapter If the textbook will be updated by authors and other contributors, it is important to know where the current text is based on. Most of the textbook is well written with clear and precise language. However, I do find sometimes the information is too descriptive and not in-depth enough. For example, in the introduction of chapter 20, the textbook provides an example of an ecosystem. It introduces the oak-pine barren as a nutrient-poor, fire frequent ecosystem, and talked about what researchers study in such ecosystems the movement of resources.

The text ends here, and if I were a student who is reading the textbook, I would like to continue to read more information about this ecosystem and how the Karner blue butterfly and wild lupine shown in the pictures have adapted to it, which is a very nice example to show student that not only nutrient rich ecosystems are important, but even ecosystems with restricted resources can support unique biodiversity.

Similarly, in the introduction of chapter 12, the textbook uses a bee and an Echinacea flower as an example to demonstrate a bee and a flower can be related. I assume the authors were suggesting the co-evolution of Echinacea and pollinators and how phylogenetically flowers became diverse, but I am not sure they might be referring to the fact that both of them are in Domain Eukarya , and nowhere could students find answers to this example. Other minor issues: Chapter The last two groups were not very clearly named and I think it is very confusing.

I recommend revise the text to lay out the four traditional groups, and then introduce the two new groups with names indicated. This textbook can be easily divided into sections and used independently. Some of the later chapters, such as the Evolution and Diversity of Life and Animal Structure and Function, do use information from earlier cell and genetics related chapters such as what is ribosomal RNA. But I think in the online version, the search box is very useful for students and instructors to locate the definition of unfamiliar terms. Students should be able to read these later chapters even if the instructor skips the molecular biology and cell biology sections.

This is especially helpful if the instructor is teaching a non-major class not aiming to cover the entire scope of biology, but only focusing on conservation biology, global change biology, etc. The information arrangement in this book follows a structure that is commonly adapted by biology textbooks, especially books for non-majors. It also introduces different foci of biology studies and how it is related to other areas in science.

I think for instructors who may want to skip some chapters to go to a specific topic in biology, this first chapter provides a functional overarching introduction of the book. My non-major class follows the same structure so it works well for me. I mostly used the online version of this textbook to do this review, and I found the links to images and outside websites in this textbook function very well.

One issue I have encountered is that the online version of the textbook mostly uses gradually reduced fonts of titles to distinguish the different levels of information within a chapter, and the difference between these fonts are not very obvious. Sometimes I get confused whether I am reading text pertaining to a new topic, or it is still within the previous section. For example, in section I assume the layout of information is Fungal Diversity Pathogenic Fungi Plant Parasites and Pathogens Animal and Human Parasites and Pathogens Beneficial Fungi But it is very hard to tell while reading the webpage because the fonts of these titles are hard to distinguish.

Another example is in chapter I recommend in addition to gradually reduced fonts, the authors can consider to use other ways such as different colors, shades, italicized fonts or bold letters to better distinguish the information nested within a specific topic. I believe open access is the future of textbooks.

The merit of this textbook is the free access and its flexibility to be modified. And yet it is peer reviewed by many contributors and users. The web based multimedia interface adds a lot of tools that make this an interesting textbook for non-major biology students. Very comprehensive and good glossary and index, as good as any of the many other texts I've seen.

Not sure if index could use some work -- for example, I could not find any reference to respiration, cellular respiration, aerobic respiration; yet, Not sure if index could use some work -- for example, I could not find any reference to respiration, cellular respiration, aerobic respiration; yet, anaerobic respiration is listed.

One thing that bothers me is Fig 1. For example, Eukarya should list Plants, Animals, Fungi, Protista, rather than slime molds, ciliates, flagellates, etc. Content appears to be up-to-date, except for that phylogenetic tree in Ch it's okay that it's the original one from Woese, but there should be an explanation that it's not up-to-date.

I believe necessary updates will be easy to make. Not sure if it's just the font being so small, but it does have a very wordy, slightly tedious flow to it. However, the animations that are built in are very good. The text is done well in regard to smaller reading sections but still has a very wordy feel to it; perhaps a larger font and more visuals would help. My students have used this text with WileyPlus for about two years now and I can't recall one complaint, whereas there were complaints about every expensive text used before that -- and I've been teaching since This book was surprisingly comprehensive.

Never using an open textbook, prior to Concepts of Biology, I had anticipated a truncated and therefore non-comprehensive textbook. However, I believe that all major concepts were covered. I primarily I primarily focused on the microbiology and ecology sections. While the depth of coverage is some sections is lacking, by which I mean things aren't covered ad nauseum, this could easily be supplemented in the classroom. Many microbiology textbooks spend far too much time focusing on every phylogenetic group, while this book chooses not to do so.

I believe this is beneficial to avoid memorization. Focus on specific groups during class time, if you wish to. The content within this textbook is relevant and will be long-lasting, while lacking in the discussion of recent discoveries in each field. Whether this is a strategy by the authors or not, I cannot tell.

This will increase the longevity of the text while putting the pressure on the instructor s to locate and present recent work in the field. Perhaps a small section at the end of each chapter addressing this would be helpful. From what I have read, this book is quite clear. The use of jargon is a necessity in a lot of chapters, but these words are explained within the text in most cases and there is also a section at the end of each chapter for definitions.

Well done. I believe the work within the textbook is consistent, I noticed little in terms of changing framework by chapter or section. I believe the modularity of this book is sufficient. Chapters themselves are modules and each is subdivided into several sections. Based on my reading of this textbook I believe the flow of organization is clear. However, as an instructor, it is possible that I am making connections between materials that would be lost on students.

Until using this textbook in a real-world situation with students, I would be hesitant to make a declaration regarding the flow of each chapter. I did not take time to verify that each hyperlink within the text was accurate, but the links I clicked to access online multi-media seemed to function. I believe this textbook represents a standard biology textbook in terms of the cultural relevance. Evolution is discussed within this textbook, so that may be insensitive to some students based on their religious ideas and relationship to their scientific studies.

The use of multimedia components helps to break up the text and engage students. At the end of each chapter there are questions to assess understanding. This, while necessary in quick review questions, aren't particularly engaging. Luckily, there are "critical thinking problems" within each chapter that can help students think a bit deeper.

Some of them were to "understand Within Chapter 1 the text addresses the difference between theories and hypotheses. Within Chapter 11, the misconceptions regarding these two terms are explained in terms of the theory of evolution. I believe a note within Chapter 1 directing students to Chapter 11, or including the misconceptions in Chapter 1, would be helpful. Snippets of "appropriate jobs" are interjected in each chapter.

This, while a bit unconventional, provides a framework for students asking "when will I use this outside of class? Within this textbook there is not much in the way of actual data to interpret or used as examples. Overall, the text is nicely comprehensive. There are a few areas of weakness, such as the following: The ecology section does not begin with an overview of ecology, which I believe is a weakness.

I would like to see a general description of the I would like to see a general description of the parts of a plant at the beginning of the section on plants Chpt 14 I would like to see answers to the questions "Art Connection" and end of chapter "Review Questions" available, but perhaps that is in the instructor support materials. I have not had a chance to take a look at those yet. The text appears accurate and unbiased, I did not note any inaccuracies. The lack of bias is significant considering that this material touches on many culturally sensitive issues.

The examples used seem quite relevant and applicable. While current and up to date, they should still be relevant for a significant time. The material is clear and concise. At times it was in a format different from what I am accustomed to seeing, which took some adaptation and additional thought. That does not mean it would be a detriment to students, who typically do not have preconceived ideas about content.

Chpt 19, for example, is not in a format which I am familiar with and would take some adjusting to on my part. Sign In Wish List 0 Help. Praise for the previous edition: "This dictionary does a comprehensive job of covering these two dynamic and expansive fields of science This dictionary provides readers with access to the basic vocabulary of modern biotechnology and genetic engineering so that even those with an elementary knowledge of basic biology and biochemistry will be able to follow any developments in this field.
