Most clubs still send catalogues and order forms via U.S. mail at least once a month. If you frequently purchase books related to a specific topic, or you're looking to start a collection of hardcover books, a book club may be the right avenue. Clubs are also likely to give more detailed descriptions and reviews of the books they offer, along with special author's interviews. Their inventory includes a few thousand titles, most of which are current and popular. This is a good source for popular fiction and nonfiction, but not the place to look for specialized books or classics.
All books are special hardcover editions.
Again, this is not the place to start a specialized library, but it is a good source for current hardcover books. Doubleday Book Clubs With its BooksOnline site, Doubleday corners the market in specialization. In addition, BooksOnline links to very specialized professional book clubs, with topics like The Mac Professional's Book Club, the Nurse's Book Society and the Nature Book Club. The Audio Book Club boasts the world's largest collection of audio books. You need to know what you're looking for, because descriptions of books are often sparse.
