Google Mashups: A New Method for Locating and Accessing Library Map Collections

Library users seeking cartographic information face the challenge of interpreting their need into the correct search terms, subject headings, or classification codes used to describe and organize maps held in library collections. Users often encounter difficulties when attempting to utilize existing access points into map collections. In fact, users frequently require an intermediary or library staff member to help them find appropriate cartographic resources.

While print and online library catalogs used to organize maps have provided adequate access to many collections, new technologies allow libraries to explore alternative, geospatial interfaces which enhance a user's ability to independently find an appropriate map. Given existing technologies, it is possible to create an online map which allows users to geographically browse for and identify needed print and digital maps.

The University of Minnesota Libraries implemented a pilot project to create a Google mashup interface which provides access to a portion of the map collections housed in several library locations across campus. Steps taken to create a map based access system included the selection, extraction, and manipulation of existing data from the online catalog and the creation of an intuitive user interface. Challenges involved in the creation and output of a geospatial interface designed to facilitate access to other maps and next steps to provide access to the entire map collection will be discussed in this paper as well.
