I am writing to this list at the suggestion of the music librarian here at UCLA. I am helping a faculty to locate basic business information (when company started and dissolved (if), record labels the company managed, number of employees and amount of camptial) for around 100 record companies between 1890-1950. The faculty member has a list of company names. However, after consulting with a few colleagues on campus, I was not still able to come up with possible sources that would provide this kind of company history as many of these company are small, private and short-lived. Any suggestions any of you may have will be highly appreciated.
