Our friends from the site Archiwum Map Zachodniej Polski have created a place-name search tool based on a US database, cross-referenced with maps available through all three partner sites, i.e. mapy.eksploracja.pl, mapy.amzp.pl, mapywig.org. and with a link to the current situation as displayed by googlemaps.
Database active at the moment includes place-names found within the current borders of Poland, Lithuania, Belaurs and Ukraine (other countries covered by the maps on our sites will follow). The database will be developed and new elements added (English interface, map calibration files, location of smaller villages, alternative place-names  and other maps). The files are LARGE - when a map is selected, the left click on the icon is to crash your browser (most likely outcome), the right click saves the file to a destination of your choosing on your computer.
In the process of preparing the project, our friends also created an index of WIG maps in 1:100 000 scale  (these are the maps listed in the Maps 1:100 000 folder on our site in 600 dpi resolution). The index can be slightly out of date at times due to a lag between us adding new files and our friends updating the index. If any files don't load, please come back to our site for the latest links.
The project includes other multisheet maps of Central and Eastern Europe in various scales, to reload them please enable java and press F5 if the site appears not to respond.
