NOTE:  See MARC 21 Format for Bibliographic Data (210 Abbreviated Title) for code definitions not given below.


Field 210 contains a title of the serial as abbreviated for purposes of indexing or identification.  An abbreviated key title is supplied by ISSN centers, based on the Key Title, field 222.  Other abbreviated titles are supplied by cataloging agencies, including abstracting and indexing services.  The abbreviated title may be created by the agency supplying the field or it may be take from the piece.

CONSER members do not input abbreviated key titles for U.S. or Canadian imprints.  Abbreviated key titles for foreign imprints that have been verified in the ISSN Register, ISSN Compact, or ISSN Online may be input by CONSER members (see C6.4.).

Editing instructions
