Joe-
Oddly enough, the process was a simple one. I visited Princeton University Press--about 10 minutes from my house--and asked if they were planning a re-issue. They told me that they weren't. I then asked if I could obtain permission to reissue it. They graciously granted it. That's pretty much the process.
    From a production standpoint, the major effort was scanning the books (actually, the hardest part was learning exactly what had to be done.) The decision to involve Loomis House was an easy one; they'd already been involved with issuing a new edition of Child, and this seemed to be a natural combination, especially inasmuch as they'd had more publishing experience than I had. Loomis House did a fine (IMO) redesign job on the cover graphics.
   We then found a print-on-demand house with both US and UK facilities, so that we wouldn't have to ship overseas. And then we published.
   I, too, had been lusting after a set of Bronson for some years, but couldn't afford a used set. The project was essentially an application of the proverbial "courteous and efficient self-service".
