Even if pieces are missing it might be a nice artifact!
(Maybe OCR or contemporary "AI" can be used to pull the image source into text with careful human review.)
Each artifact shows the importance of the people using the system for things they deemed personally interesting.
You learn more about the people, and you get a fuller picture of how the system supports various notions.
Hopefully there is enough there for a Zotero mention. (In that case just the images might be OK)
Just my 2 cents.
