Why Textbooks Cost So Much
Before we get to the solutions, let's understand the problem. Textbook prices have risen over 1,000% since 1977 — more than four times the rate of inflation. The average college student now spends $1,200–$1,500 per year on required course materials.
Why? A few reasons:
The market is captive. Your professor chooses the textbook, but you pay for it. Unlike most purchases, the decision-maker and the buyer are different people. This means publishers can charge high prices without losing "customers" — students have to buy whatever is assigned.
New editions kill the used market. Publishers release "new editions" every 2–3 years with minor changes (rearranged chapters, updated examples, new problem sets). This makes used copies of previous editions harder to use, forcing students to buy new.
Bundled access codes. Many textbooks now come with required online access codes for homework platforms. These codes can't be resold, eliminating the used market entirely.
Publisher consolidation. A handful of publishers (Pearson, McGraw-Hill, Cengage) control most of the market, limiting price competition.
The good news: there are more alternatives than ever. Let's go through them.
Free Legal Textbook Sources
1. OpenStax
What it is: A nonprofit publisher from Rice University that creates free, peer-reviewed, professionally published textbooks for common college courses.
Subjects covered: Biology, Chemistry, Physics, Calculus, Statistics, Psychology, Sociology, Economics (micro and macro), U.S. History, Anatomy & Physiology, Accounting, Business, and more.
Why it's great: These aren't amateur resources. OpenStax textbooks are written by professors, peer-reviewed, and used by hundreds of universities. They're available as free PDFs, free online reading, or low-cost print versions ($30–$50 vs. $200+ for traditional textbooks).
How to use it: Go to openstax.org, find your subject, and download the PDF. If your professor uses a different textbook, check with them — many professors will accept OpenStax as an alternative or may even switch to it if students ask.
2. MIT OpenCourseWare
What it is: Free course materials from MIT, including lecture notes, readings, problem sets, and sometimes full video lectures.
Best for: STEM subjects (math, physics, engineering, computer science) and economics.
How to use it: Even if you're not at MIT, the lecture notes and problem sets are excellent supplements to your own course. Great for when your textbook explanation doesn't click — try MIT's version instead.
3. Khan Academy
What it is: Free educational platform with video lessons and practice problems for a wide range of subjects.
Best for: Math (from basic algebra through multivariable calculus), science (biology, chemistry, physics), economics, finance, and standardized test prep.
How to use it: Use Khan Academy to supplement or replace textbook readings. The video format works better than text for many students, especially in math and science.
4. Project Gutenberg
What it is: A library of over 70,000 free ebooks, primarily older works whose copyrights have expired.
Best for: Literature, philosophy, history, political science, and classics. If your English class assigns Shakespeare, Jane Austen, or Plato, it's free here.
Limitations: Only includes works in the public domain, so contemporary textbooks aren't available. But for humanities courses that assign classic texts, this is gold.
5. Open Textbook Library
What it is: A catalog of free, peer-reviewed, openly licensed textbooks maintained by the Center for Open Education at the University of Minnesota.
How to use it: Search by subject to find free alternatives to your assigned textbook. Each listing includes peer reviews from professors so you can assess quality.
6. LibreTexts
What it is: A massive open textbook platform organized by discipline. Covers chemistry, biology, math, physics, engineering, social sciences, humanities, and more.
Why it's great: Unlike single textbooks, LibreTexts is modular — professors can remix and customize content for their specific course. Some professors build their entire course reading list from LibreTexts.
7. Saylor Academy
What it is: Free, self-paced online courses with open textbooks. Covers business, computer science, English, history, math, and more.
How to use it: Even if you're enrolled in a traditional course, Saylor's free textbooks and course materials can supplement your studying. Some courses even offer certificates.
8. Wikibooks
What it is: An open-content textbook collection hosted by the Wikimedia Foundation (the people behind Wikipedia).
Quality varies: Some Wikibooks are excellent; others are incomplete or poorly written. Check the maturity rating before relying on one.
Best for: Supplementary reference, especially for computer science, languages, and math.
Affordable Alternatives
If free options don't cover your specific textbook, here are ways to pay much less:
9. Textbook Rental Services
Chegg Rentals: Rent physical textbooks for 70–90% less than buying. Return at the end of the semester.
Amazon Textbook Rentals: Similar to Chegg, with the convenience of Amazon's shipping.
Campus Bookstore Rentals: Many campus stores now offer rental options. Compare prices with online services.
When it makes sense: If you need the exact edition your professor assigned and can't find a free alternative. Always compare rental prices across platforms.
10. Buy Used (Previous Students)
Campus buy/sell groups: Check Facebook groups, campus bulletin boards, or student forums for your specific university. Students from last semester are often selling the exact books you need.
Online marketplaces: AbeBooks, ThriftBooks, and Amazon Marketplace for used copies at steep discounts.
Pro tip: Buy at the start of semester when supply is high, sell at the end to the next cohort.
11. International Editions
Publishers sell the same textbooks in other countries at much lower prices. International editions have the same content but different covers, paper quality, and sometimes different page numbers or problem sets.
Savings: 50–80% off the U.S. price.
Caution: Check that the content matches your assigned edition. Some professors assign specific problem sets by page number, which may differ in international editions.
12. E-Book Versions
Digital versions of textbooks are typically 40–60% cheaper than print. Platforms like VitalSource, Kindle, and publisher websites offer e-books.
Pros: Cheaper, searchable, portable, instant access. Cons: Can't resell, some have time-limited access, harder to annotate for some students.
Library Hacks
13. Course Reserves
Your university library almost certainly has a course reserves system. Professors can place required textbooks on reserve, which means you can check them out for a few hours at a time (usually 2–4 hours).
Strategy: Schedule regular library sessions to read and take notes from the reserve copy. You won't have the book at home, but you can get the readings done for free.
14. Interlibrary Loan
If your library doesn't have a book, they can borrow it from another library in their network. Interlibrary loan is free for students and usually takes 3–7 days.
Strategy: Request textbooks through ILL at the very start of the semester. Some libraries will let you keep ILL books for the entire semester.
15. Library E-Resources
Many university libraries provide digital access to textbooks and reference materials through databases like:
- EBSCO eBook Collection
- ProQuest Ebook Central
- O'Reilly Learning (for tech/programming books — this alone can save you hundreds)
- JSTOR (for academic readings and some book chapters)
Check your library's website — you might be surprised at what's available digitally with your student ID.
How to Decide What You Actually Need to Buy
Before spending any money, do your homework:
Ask the Professor
Email or visit office hours and ask:
- "Is the textbook required for exams and assignments, or is it supplementary?"
- "Are previous editions acceptable?"
- "Are there any free alternatives you'd recommend?"
- "How often will we reference the textbook in class?"
Many professors appreciate students who are proactive about costs. Some will tell you honestly that the textbook is barely used, or that an older edition works fine.
Wait Before Buying
Don't buy anything before the first week of classes. Some professors list textbooks as "required" but barely use them. Attend the first class, assess how important the book actually is, then decide.
Check the Syllabus
If specific chapters and page numbers are listed, you definitely need the book. If the textbook is just listed under "recommended readings," you probably don't.
Talk to Previous Students
Find someone who took the class before. Ask:
- "Did you actually need the textbook?"
- "Could you have gotten by with the free PDF or an older edition?"
- "What resources did you find most useful for studying?"

The Older Edition Strategy
This is one of the most effective money-saving strategies, and most students don't know about it.
The concept: Buy the previous edition of your textbook instead of the current one. Previous editions are typically 80–95% cheaper because publishers have flooded the market with the new edition.
Why it works: Between editions, textbooks typically change very little. Publishers might rearrange chapters, update a few examples, or change problem numbers — but the core content is usually identical.
How to do it:
- Find out which edition is currently assigned
- Buy the previous edition (one edition back)
- Cross-reference the table of contents with the current edition to check for chapter reorganization
- For assigned readings, match by chapter title rather than chapter number
- For homework problems, borrow a classmate's current edition briefly to check if problem sets changed
When it doesn't work:
- When homework problems are different (and your professor assigns specific problems by number)
- When a required online access code only comes with the new edition
- When the subject changes rapidly (some tech and science fields)
Savings example: A textbook that costs $250 new might cost $15–$30 for the previous edition on Amazon Marketplace or AbeBooks.
Digital vs. Physical: What's Better?
When Digital Is Better
- You need to search for specific terms quickly
- You carry multiple textbooks and want to reduce weight
- You highlight and take notes digitally
- The e-book version is significantly cheaper
- You want instant access without shipping delays
- You value portability (study anywhere with your laptop)
When Physical Is Better
- You retain information better from print (research shows many people do)
- You want to annotate freely with pen and paper
- The e-book has time-limited access (you lose it after the semester)
- You can resell the physical book to recoup costs
- You find screens fatiguing for extended reading
- You want to flip between sections quickly
The Hybrid Approach
Many students find a mix works best:
- Use the free digital version (PDF) for daily readings
- Borrow or buy a physical copy for intensive study sessions and exam prep
- Use the library reserve copy when you need to sit with the text for extended periods
Semester Savings Calculator
Here's how much you can save per semester using these strategies:
Typical scenario: 5 courses, each requiring 1–2 textbooks
| Strategy | Traditional Cost | Alternative Cost | Savings |
|---|---|---|---|
| Buy new | $250/book | — | $0 |
| Buy used | $250/book | $75/book | $175/book |
| Rent | $250/book | $40/book | $210/book |
| Previous edition | $250/book | $20/book | $230/book |
| OpenStax/OER | $250/book | $0 | $250/book |
| Library reserve | $250/book | $0 | $250/book |
If you use these strategies across 5 courses: Savings of $500–$1,250 per semester, or $4,000–$10,000 over four years.
That's real money. For perspective, $10,000 is enough to cover several months of rent, a decent used car, or a significant chunk of student loan debt.
Action Plan
Here's what to do right now, before next semester:
- Get your course list and required textbook ISBNs
- Check OpenStax and Open Textbook Library for free alternatives
- Ask professors if previous editions or alternatives are acceptable
- Check your library for course reserves and digital access
- Compare prices across rental services, used marketplaces, and international editions
- Wait until after the first week to buy anything you're not sure about
- Join campus buy/sell groups for secondhand textbooks
Don't accept the sticker price. With a little effort, you can access the same education for a fraction of the cost.
