I wish I could be as optimistic regarding the entire story being told.
1. Documents deteriorate due to age and improper storage. Example, look at the
condition of page K-24 in the expanded tech version
2. Documents are misfiled in various archives or libraries and thus are for all practical purposes lost
and/or missing. This is often has to do refiling by the public in open shelf archives
3. Documents are discarded upon death of the holder because loved ones do not understand the significance of the
documents or materials to researchers
4. There may be business or government reasons for certain technologies to be supressed.
I believe the essentials are out there on the internet but that much of the techncal drawing, engineering prints and
business records are gone.
Value is a relative thing. For example, there may only be ten 1913 Coca-cola (tm) bottle caps in pristine condition, there may only be a dozen or so Gutenberg bibles, which is worth more? There may only one or two copies of Stans Master Laboratory Book in existance.
If the concepts are understood, I think the technologies will be developed, albeit in a different iteration using different materials
I would be looking at the early writings and patents. Mina has it right in terms of looking at the Genesis, the beginnings when Stan Meyer was ollowing the KISS method.

Also in the recent thumb drive, I find that there are a lot of duplicates but thay have discussion back and forth between fabricators and Stan and how they were overcoming problems with corrections in machining specifications.
