Distributors sometimes market a videorecording title as two discs, one a DVD and the other Blu-ray disc, in the same case. This creates complications because Library West decided about a year ago to create a new section for Blu-ray discs with a different accession number. Because the two formats are found together in one container under one title, it was decided that it would not be appropriate to use separate bib records. The solution was to create two separate holding records with different accession numbers based on format. Below is a brief procedure for how to do this. Eventually this will be included in a larger, updated procedure covering the cataloging of videorecordings. The following assumes that all necessary maintenance to the bib record has already been done.
