The Nason family collection, housed on site at the Nason House, consists of over 1,600 volumes and serials with a special emphasis on Mexico and Central America. The collection has a number of unique and rare items, including books focusing on the early explorations of Central America and a collection of rare archaeological items from Meso-America.  In 1992, Mrs. Nason's daughter, Alexandra Nason-Hall, donated several dozen books on art and art history to NMSU which have also been placed at Nason House.
