The Census Collections & Services LibGuide focuses on locating people in the census using microfilm housed at the University Park campus at Penn State. Individual census records can be searched online using the Library version of Ancestry.com (see below).
This guide will be useful if you have difficulties with Ancestry.com or need to double-check the information (poor image on Ancestry.com or need confirmation). It also has information on Penn State microfilm holdings of specialized censuses such the Pennsylvania Agriculture Censuses.
Individual census records can be searched online via this database.
