Not sure if this is well known to people, I just saw it today.
Apparently UC Santa Barbara library has made a large effort at transcribing and archiving thousands of vintage wax cylinder recordings. If this type of thing is interesting check it out here:
http://cylinders.library.ucsb.edu/index.php
The archive is easily searchable. They have an interesting "About" page that details the project and the methods that I found interesting too.
