The Library's printed, microform, and manuscript materials include family genealogies, publications of genealogical societies and state historical societies, local histories, vital statistics, collections of wills or deeds, military records, census material, and other categories.

Strengths are the Mid-Atlantic region, particularly Chester and Lancaster Counties, Pennsylvania, and Cecil County, Maryland.
Some materials cover the entire country.
