0.10 Change of name
Unlike previous Anglo-American cataloging codes, this code considers that a change of name by itself does not constitute a change of identity (i.e., does not create a new entity). Change of identity should be determined by means other than tying it to a simple change of name. Change in identity should not occur lightly and should be done only when there is clear evidence that most users of libraries and archives around the world would consider that two entities exist after the change, rather than one entity which happens to have changed its name. Limiting change in identity in this way will cause our entity definitions to correspond more closely with users' entity definitions and will better support international cooperation, since no other cataloging rules internationally divide person entities into bibliographic identities, corporate body entities into new corporate entities with changed names, and serial works into new works with changed titles in the same fashion that AACR2R does. If considered useful, users should be provided access to works created under particular pseudonyms or earlier forms of corporate names by means of access to transcribed statements of responsibility. For earlier corporate names, date limiting can also be used. Certain situations do constitute changes in identity. For example, when two or more entities merge together into one, or when two or more separate entities result from the split of a previously existing entity, change in identity has occurred. For serials, the beginning of a new numbering scheme signals the creation of a new serial title rather than the creation of a new work.
