Abstract
Subject headings incorporating geographic terms present a number of problems for online searching and for other purposes given the diversity of subject heading structures seen in machine readable records in the WLN (Washington Library Network) system. Factors observed include changes in heading structures, human error, the online authority verification process and ambiguities in subject heading instructions for catalogers. Problem structures and statistics for some specific heading variations are presented, searching implications and alternative heading options are examined.
