The two general kinds of book classifications in a library are the Dewey Decimal Classification system and the Library of Congress Classification system. The Dewey Decimal system categorizes books by subject based on a numerical system, while the Library of Congress system organizes books by both subject and author through a combination of letters and numbers.
