The genealogy center has over 2,000 rolls of microfilm and several important collections on microfiche and CD-ROM. This includes collections on Mexico and North America compiled by the Church of Jesus Christ of Latter Day Saints. Our microfilm collections cover the Spanish colonial, the Mexican, and the American territorial periods of New Mexican history. The Archdiocese of Santa Fe records on file cover from 1640 to 1955. Our microfilm collection includes some of the records of the Archdiocese of Durango under whose bishopric New Mexico was for two centuries.

Our Mexican collections include the important Ayuntamiento de Hidalgo de Parral, Chihuahua collection. Also in the collection are the land grant records of the state and all of the published censuses of New Mexico, including 1930. We have the censuses of Arizona and Colorado to 1920 as well. We have collected a large number of books of extractions of genealogical records, and a number of very useful finding guides. In addition we have identified approximately fifty websites worldwide that deal with Hispanic genealogy and heraldry. We have the entire run of publications of both the New Mexico Genealogical Society now on CD and the Hispanic Genealogical Research Center. We have installed several maps, which are very useful to patrons. Among them are: historical maps of New Mexican counties as they have changed over time and a 1916, 4ft.x 4ft. map of the state which shows many towns now nonexistent as well as many land grants that no longer appear on maps.
