Genealogy: City Directories


This guide is a selective list of directories. The emphasis is on publications having multiple years of coverage. The Library collection specializes in Delaware resources, but there are materials covering other areas. For example, the Library has a very good collection of city directories for Philadelphia.

Early directories in Delaware were published for the entire state of Delaware, rather than for cities.

Consult the Special Collections Department in the UD Library for more directories (

City Directories

Wilmington, Delaware, 1889 City Directory. website.
Example of a residential and business directory.

City directories are much like phone books. They typically have a list of both residents and businesses. There are also business directories and farm directories. 

Some directories have a description of the town, including street guides, government description and listings,  lists of churches, schools, libraries, charitable association, fraternal orders, and more.

When available, it is useful to consult more than one directory. Each may have some piece of information not in the other.

Business Directories

Business directories typically do not have indexes by people's names. The index is by business category. The index identifies the pages where those particular businesses are covered.

The listing identifies the owner or proprietor and the street address.

Entry in index for "pipes."

Listed as Pipes (Smoking), manufacturers of and dealers in.

Entry in directory
