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. In addition, the collection includes a number of basic texts and sources in translation. These are presented in full-text format and reproduce all the matter included in the original print version. The collection focuses upon peninsular history from the fifth to the seventeenth centuries.
