Double Bass complete orchestral bass part collections?

[JNbass]

I wanted to put together a book of the bass parts to J.S. Bach's violin, keyboard, and Brandenburg Concertos, and also the Orchestral Suites. I kind of remember there being collections on disc, of complete bass parts for certain composers (not the Oscar Zimmerman books). Does anybody know if there are collections already put together? Otherwise I will have to piece them together from imslp.

You're correct in remembering that CD collection. I recall seeing that for sale about 15yrs ago. It's probably safe to say it's not being produced anymore, since all those Bach pieces are in the public domain and available at IMSLP.
