Below is a list of all of Alexander Weinmann’s “Beiträge zur Geschichte des Alt-Weiner Musikverlages” series for easy reference. His books document the output by date and plate number of many important Viennese publishers. His papers are housed in the David M. Rubinstein Rare Book & Manuscript Library at Duke University. Many well-known (and unknown) guitarists’ publications can be researched in this series.
Based on a discussion in the Guitar Summit mailing list I am posting links to online guitar research resources.
Michael Sieberichs-Nau pointed out to me today that the Hofmeister XIX website has become public again. It is a database of the monthly music-in-print catalogue Hofmeister Monatsberichte published 1829-1900. According to the site the database contains about 400,000 records.
