I created PDFs of both books and printed them via Lulu (along the lines of Printed copy of Inform 7 Handbook available - #16 by Jonathan). It worked out as two printed volumes each (ie four printed volumes in total).
I contacted Emily Short for permission to share them here, but she said that offering printed books was something she and Graham would want to work on themselves instead. This was back in April 2021 so maybe things have changed.
