The document discusses the Dewey Decimal Classification system used by HCPL to shelve nonfiction books, movies, and audiobooks. It explains that the Dewey number (call number) puts books on the same subject together on the shelf. Each Dewey number is comprised of three components: collection indicator, Dewey number, and first letter of the author's last name. Items are shelved digit by digit after the decimal point in the Dewey number. If two books have the same call number, they are shelved alphabetically by author or title.
