En honor de la jubilación de Robert I. Burns, S.J.

The retirement of Robert I. Burns from the University of California at Los Angeles provides an opportunity for recognition of the extraordinary contributions he has made to medieval history. His numerous studies of James I and thirteenth century Valencia, his many volume Diplomatarium of documents from the Crown of Aragon Archives, the creation of a specialized library on medieval Mediterranean Spain in California and the preparation of many research students are the outstan­ding legacy of his professional career. Together with the many honours and prizes he has received, his willing and significant participation in academic symposia and the fact that he has brought Valencia into the forefront of historical studies can only guarantee him a permanent place among the distinguished scholars of medieval Spain.
