How are books organized?

Nonfiction

Nonfiction books are written to inform the reader and are rich in factual information. The TIS Library uses the Dewey Decimal System. Call numbers for non fiction books begin with a Dewey number, then the first three letters of the author’s last name, then the language code.

If you know the Dewey number of the topic you are seeking, you know that all other books on that topic have the same Dewey number and will be located together in the library.
