Not sure if it may help your Typewriter Typefaces Bible project or not, but I'll mention that Marcin Wichary used the Internet Archive to collect a lot of the materials for his massive 3 volume 2023 book "Shift Happens: A Book About Keyboards": https://archive.org/details/wicharytypewriter

In addition to lots of material which he found and collected on the Archive, he added a huge number of resources, catalogs, and books which are either rare or incredibly difficult to find by uploading them to the Archive for others to potentially find and use. You and others may find it valuable and or useful to follow his pattern of uploading and storage there.
