This bibliography of the Mexican War holdings of the libraries at the University of Texas at Arlington is the product of more than forty years’ collecting and research. As a result of his recognition that Texana collections would be incomplete without items from the period up to the ratification of the Treaty of Guadalupe Hidalgo by Mexico in May, 1848, Jenkins Garrett began this bibliography in earnest in the 1950s, at a time when Mexican War items were not even listed as a separate category by collectors. Arranged by chapters according to topics or type of holding, the bibliography is designed to give extensive and accurate descriptive information of approximately 2,500 items of interest to scholars and collectors. Each entry thus includes full title page wording, edition information, collation, other library locations, and notes, though the bibliography is not annotated per se. Extensive appendixes present alternate methods of referencing documents and compilations of data that may prove helpful in studying the Mexican War.
