Ah! Thread necromancy! I didn't mention it at the time because I was still working on it, but I was doing something similar (that I finished in Nov 2022). I compiled all the OD&D and 1e monsters from Strategic Review and Dragon into one book. Like you mentioned, it was all manual retyping. Couldn't just cut and paste from digital PDFs.
I did get the OK from Tim Kask, Ed Greenwood, and Roger E Moore beforehand, but it was couched with caution because no one really knows who owns the IP rights to those old books. Some of the rights went back to the creators and artists, and some stayed with TSR. But TSR never kept good records.
For this book, there are only a few copies: I have one, Ed Greenwood has one, Tim Kask has one, and Luke Gygax has one (Roger has a digital version).
That's awesome. Any possibility of purchasing your pdf files?
I would caution against any sort of distribution as we don't have the rights. RE: my own book, Tim Kask made it easy for me. People kept asking for a copy, so Tim mentioned in one of his videos that as the rights holder of the Bulette, he will not give me permission to distribute the book, so people should stop asking
