Apply these guidelines to multipart items that are intended to stay in one physical container as opposed to creating a separate physical "volume" for the accompanying material. These types of items may be a bound volume with a pocket containing maps, charts, etc., or a single container such as a case, box, or folder which holds several items. In these cases we are creating only one item record for the container. Each part is described within the bib record and/or the item record.
NOTE: Each multipart item needs to be evaluated independently according to the case it is issued in. For example, an original case containing multiple items may be replaced with a new case if necessary for security or preservation reasons. When in doubt, consult your supervisor.
Catalog piece with appropriate description of physical volume. Accompanying material can be described in the |e of the 300 field, in a separate 300 field, or in a 500 or 590 field note.
Add a MESSAGE field to alert public services staff to check for multiparts. It is important to be aware that only the MESSAGE that occurs first in the record is displayed to the public services staff. The internal tag for this field is "m" for MESSAGE. The MESSAGE may be either added to the item record after it is downloaded, or it may be created at the time of downloading using |m in the 945 field in OCLC. The MESSAGE should describe the multiparts as accurately and briefly as possible. If accompanying material is contained in a pocket, use: Check pocket for <describe a single item, e.g., map, 3-D glasses, etc.>, or Check pocket for <number of items> items. If multiple items are issued in a container, use: Check for <number of items> items.
For volumes with accompanying matieral in a pocket, one barcode is placed in the upper left area of the cover and one barcode is placed in the upper center of the first available leaf inside. For items issued in a container, place one barcode on the outside upper left corner of the container and one barcode on the upper center of the first leaf of the first item in the container.
