IB books 2026: The complete guide to study materials for the IB Diploma
Choosing the right IB books is one of the most consequential decisions an IB Diploma Programme student makes before the academic year begins. Get it right, and you have a structured, reliable foundation for every topic, every assessment objective, and every examiner expectation. Get it wrong, and you spend months studying from materials that either miss syllabus points or confuse more than they clarify.
This guide draws on years of experience at Times Edu working with IB students across dozens of schools and national systems. It covers the best IB textbooks by subject, how to compare publishers, where to source affordable materials, and how to integrate your books with past papers and subject guides for maximum exam performance.

Best IB textbooks by subject for IB Diploma Programme students
Not all IB Diploma [1] books are built equally. Some subjects have one clear market leader; others offer genuine competition between publishers. The table below gives you a working overview of the most widely recommended IB subject books across the six subject groups.
| Subject | Recommended Textbook | Publisher | Notes |
|---|---|---|---|
| Mathematics AA/AI | Haese IB Mathematics | Haese Mathematics | Industry standard for both SL and HL |
| Biology | Biology for the IB Diploma | Cambridge University Press | Comprehensive coverage of the 2023 syllabus |
| Chemistry | Chemistry for the IB Diploma | Cambridge University Press | Strong worked examples and data-based questions |
| Physics | Physics for the IB Diploma | Cambridge University Press | Clear diagrams; good HL extension content |
| Economics | Economics for the IB Diploma | Pearson | Aligned tightly with IB command terms |
| English A Literature | Oxford IB Skills and Practice | Oxford University Press | Best used alongside core texts |
| History | History for the IB Diploma | Cambridge University Press | Series covers all prescribed subjects |
| Psychology | IB Psychology | Hodder Education | Excellent evaluation scaffolding |
| Business Management | Business Management for the IB Diploma | Cambridge University Press | Updated for the 2022 syllabus revision |
| Computer Science | IB Computer Science | Hodder Education | Covers both SL and HL options |
One critical detail often overlooked is the edition year. IB syllabuses are revised on a rolling cycle, and using a textbook written for the previous syllabus can lead you to study content that no longer appears in examinations, or miss entirely new assessment components. Always verify that the edition matches the current IB Diploma Programme guide published by the IBO.

Oxford IB vs Pearson IB books: which should you choose?
This is the question Times Edu advisors hear most frequently from parents comparing IB Diploma resources before the school year starts. The honest answer is that both publishers produce high-quality, IBO-authorised materials, but they serve different learning styles and different use cases.
Oxford IB books are known for their conceptual depth, strong connections to the IB’s Approaches to Learning framework, and well-integrated Theory of Knowledge links. They are particularly strong in the humanities and language subjects, where analytical thinking and extended written response are central to assessment.
Pearson IB textbooks tend to be more structured and formulaic in their approach. Students who prefer clear chapter summaries, explicit command-term breakdowns, and step-by-step worked examples often find Pearson more accessible, especially in Economics and Business Management.
| Feature | Oxford IB Books | Pearson IB Textbooks |
|---|---|---|
| Conceptual depth | High | Moderate |
| Worked examples | Moderate | High |
| TOK and ATL integration | Strong | Limited |
| Best for | Humanities, languages | Social sciences, business |
| Authorised by IBO | Yes | Yes |
| Companion digital resources | Yes (Oxford Kerboodle) | Yes (Pearson ActiveLearn) |
| Price range | Mid to high | Mid to high |
A common mistake we see is students buying one publisher’s book for every subject simply because they used it in one class. The smarter approach is to evaluate by subject: use Haese IB mathematics for maths, Cambridge IB books for sciences, and then choose between Oxford and Pearson based on the specific subject demands and your personal learning style.

IB study guides and revision guides: what is available by subject
An IB textbook and an IB study guide are not the same thing, and conflating them is one of the most consistent errors students make when building their resource list.
A textbook is your primary learning tool. It introduces concepts, builds theory, and provides the scaffolding for initial understanding. An IB revision guide, by contrast, is a compressed, exam-focused summary designed for use in the final weeks before Paper 1, Paper 2, or Paper 3.
The most widely used IB study guide series include:
- Oxford IB Study Guides: Available for most subjects, these concise volumes are written by IB examiners and focus tightly on what the assessment actually tests. They are excellent for students who already understand the content and need to consolidate quickly.
- Hodder IB Revision Guides: Strong across sciences and psychology, with a particular emphasis on structured short-answer practice.
- Pearson IB Review Guides: More limited in subject range but useful for Economics and Mathematics.
- Save My Exams and Revision Village: Not print guides but digital platforms that function as supplementary IB revision resources, particularly strong for mathematics and sciences.
In our experience working with international students preparing for May and November exam sessions, the most effective revision strategy combines one authorised print revision guide with targeted past paper practice, not a second full textbook. Buying multiple textbooks for the same subject rarely adds value after a certain point.

Where to buy IB books at the best price online and in store
The cost of a full set of IB Diploma books can be significant, particularly for students taking subjects across multiple groups with different publishers. Planning your purchases early and using a combination of sources is the most effective way to manage costs.
New books: authorised online retailers
- The IBO’s own online store (store.ibo.org) sells officially authorised materials directly and is the most reliable source for verifying that a book is current-edition and IBO-approved.
- Amazon, Book Depository, and Wordery carry most major IB textbook titles and often offer competitive pricing on new copies.
- Publisher websites (Oxford University Press, Pearson, Cambridge University Press, Haese Mathematics) occasionally run academic promotions and offer digital bundle options.
Second-hand IB books: what to look for
Buying second hand IB books is a practical choice, but it carries one significant risk: edition mismatch. The IB syllabus for Biology, Chemistry, Physics, and Mathematics changed substantially between 2014 and 2023. A second-hand copy of the Cambridge Biology textbook from 2014 is not suitable for a student sitting the 2025 examinations.
When buying second hand IB books, always:
- Check the edition year against the current IBO subject guide.
- Confirm the ISBN matches a current-edition listing on the publisher’s website.
- Inspect for missing pages, missing access codes (for digital companion resources), and heavy annotation that obscures text.
Platforms for second-hand IB books
- IB Resources Facebook groups and Reddit communities (r/IBO) regularly list used materials.
- ThriftBooks and AbeBooks carry used academic stock at reduced prices.
- School-to-school handover programmes, where graduating Year 13 students sell to incoming Year 12 students, often represent the best value.

How to use IB books effectively alongside past papers and subject guides
Owning the best IB textbooks is not the same as using them effectively. This distinction matters enormously when it comes to final exam performance, and it is where Times Edu spends a significant portion of its coaching sessions.
The IB assessment system rewards students who can apply knowledge to unseen questions under timed conditions. A student who reads every chapter of the Cambridge Chemistry textbook but never practices past paper questions is not prepared for the examination, regardless of how well they understand the theory.
A structured approach to using IB books alongside other resources:
- Use the IBO subject guide as your master document. Every topic, sub-topic, and assessment objective listed there is testable. Use your textbook to build understanding of each point.
- After completing each topic in the textbook, move immediately to past paper questions on that topic. Do not wait until the end of the course to begin past paper practice.
- Use the IB study guide or IB revision guide in the six weeks before examinations to consolidate key definitions, formulas, and analytical frameworks.
- Cross-reference your textbook explanations with the mark scheme language in past papers. Examiners use specific command term vocabulary, and your written answers must mirror that vocabulary precisely.
- For mathematics specifically, Haese IB Mathematics is best used as a practice bank, not just a reading resource. Work through the exercise sets systematically, including the challenging HL extension problems if you are sitting at Higher Level.
One critical detail often overlooked is the role of the subject report published by the IBO after each examination session. These reports describe exactly what students did well and where they lost marks. They are publicly available, completely free, and arguably more valuable than any single textbook chapter.

Free IB resources vs investing in officially authorised IB books
There is no shortage of free IB Diploma resources online, and a reasonable question to ask is whether purchasing authorised IB books is genuinely necessary or whether free alternatives are sufficient.
The answer depends on your target score and your subject combination.
What free resources cover well:
- Basic topic summaries and concept explanations (YouTube channels such as OSC IB Revision and Khan Academy for mathematics).
- Past papers and mark schemes (available directly from the IBO for registered students).
- Student-created notes shared on platforms like StudyIB, Revision Village, and Litcharts for English literature.
- Subject-specific Reddit threads with examiner insights and student experiences.
What free resources rarely provide:
- Structured, syllabus-aligned progression through every topic and sub-topic.
- Exam-style questions written to match the difficulty and format of actual IB assessments.
- Detailed explanations of Internal Assessment criteria with worked examples.
- The kind of systematic coverage that IBO-authorised materials guarantee.
Drawing on years of experience at Times Edu, the students who consistently score 6s and 7s are not the ones who rely exclusively on free notes. They use authorised IB subject books as their backbone, supplement with free digital tools for reinforcement, and work closely with experienced tutors who understand the examiner’s perspective. Free resources fill gaps; they do not replace a coherent study structure.
A middle-ground approach that works well for many students: Invest in authorised textbooks for your three Higher Level subjects, where depth of content and precision of coverage matter most, and use a combination of free resources and IB revision guides for Standard Level subjects.
