CONTENT DESIGNATOR HISTORY

Indicator 1 - Specifies whether variant title and/or added entry is required (CF, SE) [OBSOLETE, 1990]
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.
