AbeBbooks

A gathering place for international bookstores, AbeBooks specializes in the creation of textbooks for the hard-to-find and has a unique ability to provide relevant articles or essays on specific topics that can aid in research and learning.

Generally, because booksellers are independent, prices can vary widely (especially when items are shipped worldwide), and can sometimes be risky if the seller is considered unreliable (on Amazon). So, read reviews and ratings before buying!

Top features:

• The site specializes in rare and collectible books, but you’ll find plenty of textbooks, too.
  
  
• Affordable international versions are available.
  
  
• AbeBooks has a buyback program so that you can make some money on your used books.
