The new MapRank search tool enables geographical searching of the collection by map location and coverage, in a Google Map window. Pan and zoom the Google Map to the area of the world you want maps of, and the results will automatically appear as a scrollable list of maps with thumbnail images in the right side window. The maps in the right side list are ranked by coverage, with the maps that have coverage closest to your search window listed at the top. Mousing over any map in the list will show the map's coverage as a light red rectangle on top of the Google Map. Clicking on a map in the list will open it in the Luna Browser. You can filter your results with the When timeline, the What or Who keyword text window, and the Map scale windows, as well as search by place name in the Find a place window.
