The quest to document one's family tree is one that stretches back across the human experience, and it can be done through the use of government records, obituaries, and so on. Recently, the Newberry Library in Chicago created this site for persons looking to trace their roots within the Windy City. First-time visitors to the site can just go ahead and type in a street address or browse through the online collections which are culled from a variety of local institutions. In the "Tools" area, visitors will find address conversion tools, Chicago City Directory street guides, and a tutorial on researching Chicago in the period before the fire of 1871. Visitors also have the opportunity to add content information to this interactive resource, which it should be noted is open source.
