worldcat lists the institutions with this book https://search.worldcat.org/title/1048005393, you’ll probably have to show up in person. You may be able to do an inter-library loan if your local library doesn’t have the book, you could get it from a sister library. However, the only public library that lists having the book is the Austin Public library in Austin, Texas.
I do this, but with keepass (keepass on all devices and then sync with nextcloud). Saved my butt a few times, I can go into the file history and pull an old version of the keepass db out of it, and then keepass has a merge feature, so I can pull the old file out, and merge with current to find missing records.
Anyway… backups good.
