Directories are alphabetical lists of names and addresses. These often list all the adult residents or tradesmen of a city or area. Twentieth century telephone books are a type of directory.

The most helpful directories for genealogical research are city directories of local residents and businesses. These are published periodically and may include individuals’ name, address, occupation, and spouse and other helpful facts. An individual’s address can be very helpful when searching in a large city with several parishes or if you are searching for the family in a large city in the 1930 census. Directories sometimes have city maps and may include addresses of churches, cemeteries, civil registration offices, and other locations of value to genealogists.

The Family History Library has very few directories for Mexico. Those the library has are listed in the “Locality” section of the Family History Library Catalog under:
