I've redone my Web site to be what Google calls "mobile-friendly"
and that's changed the link addresses.  For those of you who saved the
addresses of the Rollographies, the PV Phonoliszt-Violina Rollography
(all 930 original rolls) can now be found at

  http://rickcrandall.net/wp/pv-rollography/ 

The O-Rollography now has over 700 original O-rolls catalogued, with
tunes dated and composers identified thanks to a cooperative effort of
many collectors contributing roll information and Matt Jaro's amazing
data base:  http://rickcrandall.net/wp/operators-o-roll-rollography/ 

If you don't record these links you can always find them under "music
machines" at http://www.rickcrandall.net/
