The goal of the EDVR project is to eventually list all recordings--published and unpublished--made by The Victor Talking Machine Company and its successor RCA Victor through the end of the 78-rpm era in the 1950s.
The EDVR home page interface is intuitive, and contains two primary menu tabs: Browse and Search.
E-mail addresses of the staff are given under the "About EDVR" page.
The home page notes that the EDVR "includes master recordings made by Victor in the United States and Central and South America, releases derived from masters recorded in Europe by the Gramophone Company, and trial recordings of new artists and sessions from which no discs were issued." In the case of tenor Francesco Tamagno's 1903 G&T recordings that were made in Italy, all eleven issued by Victor are listed.
