Through my involvement with GeoRef for the last twenty-five years, I have become interested in the use of geographic identifiers for search and retrieval in bibliographic databases.  The GeoRef database is a bibliographic geoscience database referencing studies of the Earth throughout the world.  Defining specific geographic areas is essential to usage of our data and, as part of that need, we have developed controlled terminology for approximately 13,000 geographic areas. Where possible we have also defined these areas using latitude and longitude boxes.
