Step 1
Start with the Library of Congress. They have cataloged practically every edition of every book published in the United States, and they have an extensive collection of rare and antique books that can help you start your research.
-
Step 2
Know your budget. Purchasing an antique book can run into the thousands of dollars, or they can be found for far less.
-
Step 3
Look for first editions of famous books, such as the works of Mark Twain or Charles Dickens. First editions are usually very rare and often valuable.
-
Step 4
Look for editions of books with typographical errors in them. These are pulled from the shelves almost immediately and thus become very rare and valuable.
-
Step 5
Check out your local used bookstore. They may have a few rare or out-of-print books on a back shelf somewhere. Or if they don't, they may at least be able to give you some tips on how to start your collection.

Step 6
Be aware that the Antiquarian Booksellers' Association of America (ABAA) publishes an annual directory of antique booksellers in the United States. Write to them to see if you can find an antique bookseller near you. See the Resources section below for a link.
