Berthold fonts used to be available through Adobe. I have the entire Adobe library including the Berthold Exclusives. Berthold took bankruptcy a few years ago (piracy and illegal duplication). When they emerged from bankruptcy it was with new ownershop and they did not choose to reinstate their agreements with adobe and others.
I've been using Catull occasionally since 1991 when I first acquired the family as a type dealer for The Font Company (Now out of business).
