Thank you! Another commenter mentioned they found a book by the same name on MAM, but by an author I didn’t see mentioned on the publisher’s site, so it’s very likely a separate work by someone else. It is fairly huge, so making a digital scan is a project in and of itself.

This is the official URL.

From the excerpts on the site, there wasn’t any 1 specific author (I didn’t see anyone with the name you mentioned in my skim), but several contributors, since it was a Kickstarter project funded by interested parties who wanted a modernized and compiled version of all 13 volumes in 1 book.

Thank you either way! You didn’t have to do that, but you did which I’m very thankful for! ☺
