I meant to post this right after getting home from SLICS, but forgot until today.
I spoke with Bill Woodin at SLICS about when we might expect to see Vol. III.
He told me that the text is completely done, arrangements for publication have been made. The only hold-up is waiting for Gene Scranton to complete the drawings. Bill said he hopes to get it out next Spring or early Summer.
So, don’t give up hope. With any luck we might have Vol. III by SLICS 2011.
