I used to collect these items, but The Griffith Project books are extremely expensive. The ones I am missing are volumes 3, and 8-12. I am not really all that interested in 11 and 12, but if I could find them cheap, I wouldn't pass it up. I periodically do searches to see any of them turn up for a reasonable price, but that's unlikely. Just putting this out there in the unlikelihood that someone would have a tip.
As for Griffithiana, I have all the issues that are in English except for the last one (73/74). I ended my subscription when it appeared they were done, but then they put one more out. Anyone know if Livio Jacob sells them?
