A commercial network of nearly 9000 independent booksellers, abebooks.com is an excellent source for those users looking for out-of-print, rare, or used books. With a database that offers over 30 million books, the site provides advanced search capabilities, full e-commerce options, and a user-friendly interface. Also of note, the site recently extended into the international marketplace, purchasing JustBooks and, in the process, adding not only French and German books to their network's inventory but also language-specific customer service and purchasing options for French and German customers. Librarians should also take special interest in this second site -- a service tailored specifically to the needs of librarians (requires free registration). This site facilitates the sometimes difficult process of locating hard-to-find books.
