This bibliography is the first part of an update of the "Western European Dissertations on the Hispanic and Luso-Brazilian Languages and Literatures: A Retrospective Index (1984)," which lists 6,050 dissertations from the early 19th century through 1980. Twenty universities on the Iberian Peninsula granted approximately half of the total for Western Europe. The scope of the 528 dissertations listed in this supplement is limited, with a few exceptions, to doctoral dissertations on the Romance languages and dialects of Portugal, Spain, and Ibero-America. Also included are studies of bilingualism, translations, and pedagogy involving Catalan, Galician, Portuguese and Spanish. Dissertations on aspects of second language teaching or learning are listed, and studies and editions of historical documents, "fueros," chronicles, and histories of the Middle Ages are included. Entries are also given for studies of library collections, archives, and the press. This update was made through study of records at universities in Madrid and Lisbon and consultation of other published sources. The bibliography includes an author list and an index.
