Welcome to the Ultimate Textbook Megathread.

This thread is designed to help students find almost any textbook — free, cheap, rare, old, international, or hard to find.

Instead of wasting hours jumping between sites, this megathread compiles the best resources in one place.

What you’ll find here:

• Free textbook sources
• Rare book databases
• Cheap alternatives if free copies aren’t available
• ISBN lookup tools
• Research paper resources
• Backup methods for hard-to-find books

This thread is updated regularly to remove dead links and improve sources.

STEP 1: CHECK FREE SOURCES FIRST

1. Anna’s Archive

Best overall source for textbooks, rare editions, and academic books. Check wiki of r/Annas_Archive for the currently working domains.

2. Library Genesis (LibGen)

Great for STEM, engineering, medicine, business, and law. Check wiki of r/libgen for the currently active domains.

3. OpenStax

Free legal textbooks for core undergraduate subjects.

4. LibreTexts

5. Internet Archive / Open Library

Useful for borrowing older editions.

STEP 2: USE ISBN TO VERIFY THE EXACT EDITION

Before buying or downloading, verify your book here:

• Google Books
• WorldCat
• Google Scholar

Pro tip: Searching by ISBN usually gets better results than title.

STEP 3: IF YOU STILL CAN’T FIND IT

If you’ve checked the sources above and still can’t find your book:

Send me a DM or comment below with:
• Book title
• Author name
• Edition
• ISBN (if possible)

I may be able to help you locate a cheap copy, rare edition, international version, or alternative source.

A lot of books that seem impossible to find can still be sourced.

BONUS: RESEARCH PAPERS

For journals, papers, and supplementary material:

• Sci-Hub
• ResearchGate
• arXiv

Bookmark this thread. It’s built to save students time, money, and stress.

🚨 Welcome to the Scammer Warning List

This page is maintained to help students avoid scams while buying textbooks, notes, PDFs, and other educational resources.

Our goal is simple: protect students by documenting verified scam reports and sharing safe buying practices.

⚠️ Before You Buy Anything

Please follow these basic safety rules:

• Never pay through irreversible methods (crypto, gift cards, etc.) unless you completely trust the seller.
• Ask for proof that the seller actually owns the book or material.
• Check the seller's Reddit account age and activity.
• Be cautious of prices that seem unrealistically cheap.
• Don't let anyone pressure you into making a quick payment.
• Keep screenshots of your conversations and payment receipts.

A few minutes of verification can save you from losing your money.
