Index map

Index map

Index maps are a type of finding aid that allow users find a set of maps covering their regions of interest along with the name or number of the relevant map sheet. An index maps provides geospatial representation on either a sheet of paper or a computer screen. In this way, a map acts as a kind of gazetteer, with the location (such as a call number) represented within a grid overlaying the maps surface.

One important need for geospatial data such as this: political borders often change. Information is being searched by coordinates, rather than the metadata for a particular country and region that can be entered into a catalog. Additionally, in various institutions, maps are sometimes cataloged individually or as sets, resulting in various levels of specificity.
