In addition to its own catalogue of sources, the Digital Resources in Musicology showcases “ADAM: Archive of Digital Applications in Musicology, EVE: Electronic and Virtual Editions, and Harvard’s Online Resources for Music Scholars.” The repository, which serves as a vast collection of ideas and information, aggregates study and research information for scholars. Within its categories, it provides links to GIS maps from different sources around the world – some of these maps show information from antiquity, while others include more modern information.
