This document discusses how library catalogs provide subject access to works of fiction. It outlines how genre terms from the Guidelines on Subject Access to Individual Works of Fiction, Drama, Etc (GSAFD) are used in MARC records to help patrons find fiction by genre. The GSAFD list of 153 genre terms has been developed into MARC authority records. Libraries use genre headings from GSAFD in the 655 or 690 tags to help patrons identify the kind of fiction they want more easily than subject headings alone.
