The Düben Collection Database Catalogue is a digitised catalogue presenting meta-data and scanned facsimile of the manuscripts in the Düben collection, a large and important collection of musical manuscripts and prints from the 17th and early 18th centuries. The Catalogue is managed from the Department of Musicology at Uppsala University.
The Aria Database is a collection of information about opera and operatic arias. Besides providing basic information about each aria, the Database includes translations for many arias and aria texts for those that are not affected by copyright restrictions. The Database also provides access to a collection of operatic sound files to give visitors an idea of what each aria sounds like.
The Aria Database was created and is maintained by Robert Glaubitz. He resides in Edmond, Oklahoma, where he has been an assistant professor of voice at University of Central Oklahoma since 2009.
