The Mexican sheet music collection is compiled of a variety of musical scores of Mexican and Latin American music that was published in Mexico, other parts of Latin America, the United States and Europe. Musical genres represented in the collection include canción, canción mexicana, canción regional, fox-trot, march (marcha), bolero, waltz (vals), danza, tango, huapango, schottisch, corrido, son, polka, romanza and a few others. Most of the scores contain beautiful cover illustrations. The musical scores have been divided into twenty-seven folders, based mainly upon the alphabetical titles of the songs. If songs begin with the article el or la, the items have been filed within the alphabetical folder of the following word (example: El Abranico is filed under A). In addition to the alphabetical divisions, the Mexican Sheet Music collection has three folders of published collections of Mexican music (containing at least two or more songs), as well as an entire folder of music published outside of Mexico. Within this collection of musical scores, there are a significant number of works by renowned composer Agustin Lara, as well as numerous scores written by Alonso Esparza Oteo, María Grever, and Carlos Espinosa de los Monteros. Additionally, an entire folder consists of the serial publication Cancionero del Bajio, which regularly published the lyrics and music for folk and popular songs.
