I just wanted to spread the word about our new Chicago genealogy website, ChicagoAncestors.org.
It's an interactive map of Chicago on which we've plotted information of interest to genealogists and local historians. We first launched it in August at the FGS conference, but we've just added some new interactive features this week. Users can now add their own map points and add comments to others.
The software that we created for the map is open-source, so if other organizations are interested in creating a similar project for another locality, there is no licensing fee. Let me know if you have comments or questions.
