The Library of Iberian Resources Online (LIBRO) is a joint project of the American Academy of Research Historians of Medieval Spain and the University of Central Arkansas. Its task is to make available to users the best scholarship about the peoples and nations of the Iberian peninsula. Consequently, the book list is principally drawn from recent, but out-of-print university press monographs. These are presented in full-text format and reproduce all the matter included in the original print version. Initially, the collection focuses upon the Hispanic Middle Ages, ca. 500 to 1500, but will eventually expand to include titles from the sixteenth and seventeenth centuries as well.
