a. Notes for parts that are not separately cataloged:

When all parts are covered by one record, give a note in field 515. Whether or not the note is general or specific depends on whether the parts have separate titles, the likelihood of the titles remaining constant, and their overall importance. For example, if an annual is issued each year in two parts with very distinctive titles, a 515 note listing the titles might be given. If the titles are likely to be searched by a user, consider giving an added entry for each in field 730. On the other hand, if an annual directory is issued in four volumes and the part titles consist of a geographic or alphabetic breakdown of the contents, the part titles consist of a geographic or alphabetic breakdown of the contents, the part titles should be omitted. The number of parts and titles may be mentioned or noted, depending on the likelihood that this information will remain constant. When cataloging a new item, it is best to give a general note; otherwise the information may soon need to be revised.
