Comments on Example

Many times in cataloging non-print items for a library, there is a concern with the title information. AACR2 rules specify that the title listed in the title and statement of responsibility should be taken directly from the item being cataloged. This works quite well with a book that has a title page. Problems arise with non-book items that have one title on the item, but another title listed on the documentation accompanying it, and perhaps a third title on the package. These titles may all be similar, but there is a problem with how to list these variations in the cataloging record. A patron may remember one title, and perhaps it will not be the one on the item itself. MARC allows for this type of situation by having a field, 246, that is specifically for variations in the title. In this case there are two different variations that are listed. Having these variant titles in the 246 field will allow them to be searched just like the title in the 245 field when a patron is looking through the library catalog.

Also, in looking at the tagging for this item, it should be noted that several of the fields are missing. There is no 100 field for this computer program. This means that this encyclopedia does not fit into the rules for an author main entry as outlined in the AACR2. Because this is a title main entry, the 1XX section, Main entry, is not needed. Also, there are no added entries in the 7XX section for personal names, just ones for corporate names (710). These details are important to pay attention to when doing original or copy cataloging in the MARC format.
