Why are City Directories Important to Genealogists
Individuals that research their family history use a variety of sources. Those sources vary, depending on each persons research knowledge, affordability, and availability of resources.
Census records are the number one U.S. resource used by genealogists. Other data sources would include Tax Records, Military Records, Ship Passenger Lists, and City Directories, etc.
City Directories are often over looked by researchers, yet they can identify almost every household every year. They can also help distinguish different persons of the same name. They are easy to read, alphabetically arranged, and contain a wealth of information.
MyGenealogyStore.com also has digital census CDs, microfilm readers, and other genealogy books available.
