Tony Orbasido was running the American Federation of Musicians' Local No. 6 in San Francisco when I started asking him about researching in whatever papers they had. What they had was two 4-drawer filing cabinets stuff with studio recording contracts. I think the union didn't keep gig contracts in hard copy beyond 3-4 years for space reasons, and there were no gig contracts relevant to me.
This was before I could take legible cellphone pictures. I had to run Xerox copies of what I wanted. In later years, I progressively digitized these paper copies. The sample is biased with respect to anything in the Garciaverse, because I was explicitly looking for and only gathering out to Spudfactor = 1 musicians, in addition to Garcia himself. As I have reported, the Jerry Garcia and Grateful Dead contents of these files was dramatically light. I think Tony O said someone had come through and gathered them up. This could well have been the Jerry Garcia Estate, but I do not know that. Anyway, within the limits of the media I was working with, I was able to go through 1967-1972 pretty thoroughly.
I published the Garcia-relevant stuff in batches. By way of making an index, here they are.
