In the past, the SEO cataloging team suggested that DVD/Blu-Ray combo packs that the set be separated, and the discs cataloged on a DVD record and the Blu-Ray record. However, if the set were not separated, a separate combo pack record would need to be added to WorkFlows. The addition of a separate record could cause confusion with library users and staff as there would be a DVD record, and two Blu-Ray records, one for the solo Blu-Ray and one for the combo pack.
The technical services committee discussed this practice and have recommended that combo packs no longer need to be cataloged on a separate record. Instead, if you have a combo pack, it can be cataloged on the DVD record OR the Blu-Ray record, whichever works best for your library. We still encourage separating the discs.
