Fixed Fields Coded Data for Geo-Related Information in the MARC21 Structure: A Discussion on the Possible Expansion of Coded Data Elements to Improve Machine Manipulation and User Discovery

Patrons of map collections often have specific, geographically-based, requests for maps and the information they provide. Map librarians can often meet these needs through personal knowledge of the scope of their collections. For larger collections, this method is unsustainable. This article, therefore, seeks to begin a discussion on how coding could be used to expand the ability of our patrons’ online information seeking methods to meet their information needs.
