At http://www.mechanicalmusicpress.com/  we include several major rollographies and links to others, all in one place.  We're always interested in adding more links.

Terry Hathaway has spent years meticulously compiling these.  Each of his rollographies begins with an opening descriptive page.  At the bottom of the page are buttons which open reports that are sorted in various ways.  All of Terry's reports are created from master relational databases, making the various sorts possible: by roll number, tune title, and in some cases, composer.  Another button at the end of each page leads to instructions for reporting additions and corrections.

Please submit links to other rollographies to webmaster@mechanicalmusicpress.com.geentroep [delete ".geentroep" to reply].  All types of existing rollographies are of interest (reproducing piano, player piano, orchestrion, organette, band organ, pipe organ, etc.) We do not have time to create new rollographies.  We encourage anyone who is working on one to report it to MMD and to us, to avoid redundant efforts.
