Afternoons with Hiller?

For those of you who were wondering, the title of my blog is sort of an inside joke between me and a couple of my co-workers in the Music Library. It refers to a project that I have taken over from one of the Student Assistants -- I am trying (desperately) to identify a dozen or so flowcharts for computer music composition belonging to the Lejaren Hiller Collection at UB.

Hiller created these flowcharts as ways of composing music with computers, and when he died they were donated to UB by his widow. They apparently sat in storage, rolled up in paper, for about 20 years, the problem being that when you let something sit rolled up for that long, the minute you try to unroll it, it's pretty fatal. When the archivist tried to unroll the flowcharts and preserve them, all of these tiny little glued-on labels popped off. Hence, we are trying to identify the flow charts, glue the teeny-tiny labels back on, and preserve them. They are all labeled with figure numbers, leading us to believe that they are published in an article somewhere. The problem I'm coming up against is that no one, and I mean NO ONE -- except for Hiller and people that wrote with Hiller -- has written about these flowcharts or his computer music composition.

So where does that leave me? Right now, I have about 20 things ordered through ILL, and those books and articles that I have already received from ILL have led me nowhere. I'm hoping that something comes in that can be a beacon that leads me to the proper identification and preservation of the remaining charts.
