In the late 1960s, 16 universities formed the Texas Consortium to Microfilm Mexican Archival Resources. The coalition was formed in order to preserve irreplaceable Mexican archival records which, at that time, were in danger of permanent loss. Some projects, like Trinity's efforts in Nuevo Leon and Coahuila, were completed, while others were never started. Today, documentation of these collections is poor, and institutional memory is beginning to fade. Trinity's collection has not received any descriptive attention since a finding aid was created in 1986. Moreover, records of the microfilm are not in Trinity's OPAC and thus are hidden from scholars who might otherwise benefit from their use.

David B. Adams, professor emeritus at Missouri State, made frequent use of the collection from 1984 through the early '90s. This research culminated in the publication of two articles: “Embattled Borderland: Northern Nuevo León and the Indios Bárbaros, 1686-1870,” published in Southwestern Historical Quarterly, and "At the Lion's Mouth: San Miguel de Aguayo in the Defense of Nuevo León, 1686-1841," published in Colonial Latin American Historical Review. Likewise, Elisabeth Butzer, of the University of Texas at Austin, drew on Trinity's microfilm while researching her 2001 monograph Historia Social de una Comunidad Tlaxcalteca: San Miguel de Aguayo (Bustamante, N.L.), 1686-1820.
