Research Prompt: What about Harvey Pekar's music and book criticism?

I usually swim a mile a day for exercise, and think deep (hah!) thoughts about comics during that time. I would usually call John on the way home from the pool with a new idea for IJOCA - much to his amusement. Here's the last one that I never got around to sending to him...

This one is more in the way of a personal wish list. Years ago, when I compiled the interview book Harvey Pekar: Conversations, a lot of what I found by Harvey was actually book and music reviews that he'd written for a wide variety of publications. Harvey was an autodidact, and did an impressive amount of reviewing, presumably for his interest, but knowing him, also for the money and the free publication. At the time, I had the idea that I would go back and propose a collection to him and his wife Joyce Brabner. They both passed away and many years have gone by and I still haven't done it. At the very least I think a bibliography of them would be an of interest. 

However an edited collection would be even more useful, and one could get at least a conference paper and a journal article out of it before compiling them into the book. I'm pretty sure the University Press of Mississippi would publish this. Does anybody know who holds the rights to Harvey's estate now?
