Index Maps in EarthWorks

Index maps, a kind of finding aid for navigating large sets of maps geographically, are now available interactively via EarthWorks. The Stanford University Libraries (SUL) have been publishing digitized maps online for many years, and in the past two years georeferenced maps, along with geospatial data, satellite imagery, and aerial photographs have been made more easily discoverable via EarthWorks, but index maps have posed special challenges. Thanks to cooperation between the staff of the Stanford Geospatial Center and the EarthWorks development team in Digital Library Systems and Services (DLSS), these maps are now more easily discoverable and navigable.
