City directories are a valuable genealogy resource.  They can give information on household composition, residence and business location, and insights into the lives our ancestors led.  They can also be used as a substitute for the US Federal Census, or used in conjunction with the census to locate hard-to-find ancestors.  This class explores the history of this resource, the research value of the information they provide, and where to find the records.
