PhiloBiblon
PhiloBiblon is a free internet-based bio-bibliographical database of texts written in the various Romance vernaculars of the Iberian Peninsula during the Middle Ages and the early Renaissance.
PhiloBiblon (which takes its name from Richard de Bury’s 14th-c. description of an ideal library) is the corpus of data catalogued by the PhiloBiblon Project: the romance vernacular sources of medieval and early modern Iberian culture. It is also the bio-bibliographical database management system designed to catalog the primary sources themselves, both manuscript and printed, the texts they contain, the individuals involved with the production and transmission of those sources and texts, and the libraries holding them, along with relevant secondary references and authority files for persons, places, and institutions (text from the PhiloBiblon home page).
