There are song recordings listed on the UNM Library computer. Some are at the Fine Arts Library and some are at the CSWR.
Also use the ROCKY MOUNTAIN ONLINE ARCHIVE (RMOA) engine to search for sound recordings, sheet music or song lyrics in the inventories of archival collections at the CSWR.
(The RMOA can also search the inventories of collections at over 30 other repositories in NM, CO and WYO).
Here are the lyrics for a song about New Mexico women voting that I found in the New Mexico WPA Collection.
Use Advanced Search. Limit by institution = UNM Center for Southwest Research (or can open to all.)
Use keyword to search for topic.
Use the Word search box for your topic.
The blue highlighting reveals briefly what is inside that collection.
You can click open the collection (red highlighting). When looking inside an individual collection inventory, use CTRL + F to open a Find window – then type in your search term to locate it again in the inventory.
