The Historical New Haven Digital Collection was created in the Summer of 2003 as an on-line resources in support of New Haven and the Problem of Change in the American City (PLSC 251a/HIST 151a/EPE 385a/ARCH 385a).

The Digital Collection contains over 500 images of historical New Haven, as well as over 75 documents containing key census information and other data from New Haven over the past 150 years. An extensive map section on the website allows you to compare maps of New Haven from different time periods at the block- and even building- level; the maps can also locate addresses and major features like churches and local parks.
