The Cataloging Advisory Group worked with SWAN to separate genres out of the Subject facet into a new Genre facet. This new facet will be available in your Enterprise catalog starting early next week.
These terms are held in the 655 field of our bibliographic records and are primarily sourced from the Library of Congress Genre/Form Terms with some exceptions. If you are looking closely, please note that we have suppressed terms that duplicate other search facets, such as those that only refer to format or age level, so not all entries in every bibliographic record will appear.
You can see it in action on the default SWAN catalog at https://catalog.swanlibraries.net.
