Yeah, this subject is a bit of a rabbit hole. I've read about half of the so far. That's my list of sources from those that I have so far.

I would say start with:

* The Notebook: A History of Thinking on Paper by Roland Allen (This is a fast micro history that hits the highlights.)

* Too Much To Know: Managing Scholarly Information Before the Modern Age by Ann M. Blair (She is a scholar that has a lot on the subject.)

* Forgetting Machines: Knowledge Management Evolution in Early Modern Europe by Alberto Cevolini (This is a collection of pretty deep essays.)

* Paper Machines: About Cards & Catalogs by Markus Krajewski (This is about the development of paper-based databases.)

Thanks for taking the time, I appreciate it. If you write anything on the topic I'd be interested in reading it.
