Guide to the Dewey Decimal System

The Belvedere-Tiburon Library uses the Dewey Decimal System to classify the nonfiction books in its collection. The only exceptions are poetry and works of classic literature, which are found in the 800s. Fiction, Mystery, and Science Fiction can be found in their own sections and are organized by author, e.g. Fiction Faulkner. Biographies are also in a separate section, organized by the subject of the biography, e.g. Bio Roosevelt.
