For a number of years, according to the Levels of Cataloging policy, pop-up books were supposed to circulate on either PERM or GENERIC records. However, in practice many pop-up books were fully cataloged. It wasn't always apparent that a book was a pop-up at the point of order. Given that pop-up books have often been cataloged, the Collection Maintenance Subcommittee opted to officially change the Levels of Cataloging policy so pop-up books will receive full cataloging. To that end, the following policy change was approved by the ILS Committee on December 5, 2018:
This means that pop-up books will receive full OCLC MARC cataloging. Moving forward, library staff can now create BSE records for any pop-up books without an existing match in Koha. The Books BSE section of the Linking Manual has been updated to reflect this (see Section V: Books, pg. V-22, under 250 Edition). When adding a BSE record for a pop-up book, staff can enter [Pop-up book] in the Edition field to note that the book is a pop-up. When the book is cataloged by Madison staff, they will also add a genre heading for Pop-up books.
