Content designator history:

First indicator - Specifies whether variant title and/or added entry is required  (CF SE)  [obsolete, 1990]

The first indicator was originally defined to specify whether the key title was the same or a variant of the title proper in field 245 and was used by LC to generate or suppress the 245 title in records sent to the International ISSN Center:  0 (Key title is same as field 245), 1 (Key title is not the same as field 245).

In 1977, this indicator was redefined to indicate whether an added entry was needed in addition to whether the title was a variant, and values 2 and 3 were defined.  The four values were:  0 ((No key title added entry; title proper same), 1 (Key title added entry; title proper different), 2 (Key title added entry; title proper same), 3 (No key title added entry; title proper different).

In 1990, the first indicator was made obsolete.

In pre-AACR 2 records, the first indicator was also used to generate an added entry for the key title.  The display constant for the tracing was:  Key Title.
