According to the site's homepage, "Historic Pittsburgh is a comprehensive collection of local resources that supports personal and scholarly research of the western Pennsylvania area. This Web site enables access to historic material held by the University of Pittsburgh's University Library System, the Library & Archives at the Heinz History Center, Carnegie Museum of Art, Chatham College Archives, Pittsburgh History & Landmarks Foundation, and Point Park University Archives."
The collection is divided into seven basic parts. In the "Full-Text Collection," users can search or browse more than a thousand "books published in the nineteenth and early twentieth centuries." There are five series of maps available, although some of these are still being loaded onto the site. There are more than 11,000 images available for searching or browsing. There are searchable census records for 1850 through 1880. A chronology covers Pittsburgh's history from 1717 to 2008. For those in the area, it also has a collection of archival finding aids and the catalog of Historical Society of Western Pennsylvania (HSWP) at the History Center.
In addition, there are links from the homepage to "News" (announcements of updates for the site), "For Teachers" (two suggestions for how the site might be used by middle school teachers), "About" (which gives the history of the project and the names of all the institutions involved), "FAQ," "Related Sites," and "Site Map."
