Disk 1 of 2 4. DRA item notes. This functionality is little understood by Davis cataloging staff, and some did not realize that catalogers could create such notes. Most items in the UNC-CH system will be housed inside or with the primary format. If the primary format is a volume, and the accompanying material can fit into an existing or easily manufactured pocket, the material will be put inside it.
Libraries often find the existing pocket inadequate, and replace it with a better one.
Increasingly, better ones are of plastic, often polypropylene. Some libraries recommended manufacturing Velcro closures for pockets to keep light items from falling out. If the material will not fit easily inside the primary format, there are at least two alternatives. HSL uses a separate enclosure for all accompanying items with a plastic insert and pamphlet binding, to be shelved beside the primary item. Another idea from the field is to enclose the primary and secondary items together in a custom-made phase box.
