Initiated in the fall of 1989, the U.S.-Mexico Interlibrary Loan Project is a cooperative effort providing for the formal exchange of books, photocopies, and microforms between libraries in the Southwest United States and Mexico City. The 25 U.S. participants are all members of the AMIGOS Bibliographic Council and are primarily academic libraries. The Mexican collaborators include six libraries at private colleges and universities and the Benjamin Franklin Library of the United States Information Service. The University Library of the University of Texas at El Paso coordinates the program, the first of its kind between the United States and its neighbor to the south.
