Tip #156: The first indicator in the 245 field is not always a ‘1’

The first indicator of the 245 field must be either a ‘1’ or a ‘0’. Which one to use is determined by whether or not the title is the main entry for the record.

What’s a main entry? It’s the primary heading for the resource you are cataloging. Added entries are the secondary headings. Subject headings (6xx fields) are always added entries. Remember card catalogs? The main and each added ‘entry’ had its own catalog card, with the heading typed at the very top.

How to tell if the 245 is the main entry:

  1. If there is a person or corporate body primarily responsible for the intellectual or artistic content of the resource, then that is the primary heading, or ‘main entry’. The name of the person or corporate body is in the 1xx field. The title of the resource (the 245 field) is then called the ‘added entry’ because it’s not the primary one.
  2. If there’s no person or corporate body that qualifies as a primary heading, then the title of the resource (the 245 field) is the main entry. There would be no 1xx field in the record. An exception to this would be if the title needs to be made either unique or consistent with the title given on other versions of the work. In that case, there would be a uniform title in a 130 field and that would be the main entry rather than the 245.

So here’s the rule: If a record has a 1xx field, then that field is the main entry. If a record does not have a 1xx field, then the title (the 245 field) is the main entry.

If the 245 field is the main entry, then the first indicator is a 0. If the 245 field is an added entry, then the first indicator is a 1.

IN A NUTSHELL: If there is a 1xx field, then the first indicator of the 245 is a 1. If there is no 1xx field, then the first indicator of the 245 is a 0.
