I'd tried doing it on the cheap in my last house, and I was able to make my collection more personally accessible, but I was still resigned to doing my writing elsewhere. In my new house, I've been able to really design it to suit my needs and it's already working exactly how I hoped it would. This week, I've gotten all the major components in place, and I thought I'd share something of a tour.
First, here's my main workspace. I've got my computer and microfiche reader side-by-side, and all of my reference books about comics and comic creators right there. (They still need to be alphabetized, though.) Right underneath my microfiche reader is a portfolio of original art that I don't have room for on the walls. The smaller bookshelf on the right has books on comics fandom and my meager collection of comic strip reprints.
