Some possible/not possible sources that could be used to manually bootstrap content:
- LibreTexts. Good project. "Teacher-only-content" unfortunately as usual. But besides that fundamental flaw, they do exactly what we want to do in a sense.
- OpenStax: CC BY. This could be a great entry point, as they already have some university integration going on, and might be interested in this project.
- physics.stackexchange.com/questions/6157/list-of-freely-available-physics-books "List of freely available physics books" explicitly asks for:but the thread was locked, and basically none of the sources in the answers have free licenses, nor do they note it. It just seems that the physicists don't know what a free license is.
a list of physics books with open-source licenses, like Creative Commons, GPL
- MIT OpenCourseWare: CC BY-NC-SA, so not really usable
- github.com/certik/theoretical-physics: MIT License. Workable but wonky.
- subwiki.org/: wiki with some upper graduate math subjects presumably by this Indian dude: www.linkedin.com/in/vipul-naik-0ab1898/. Description on his homepage: vipulnaik.com/subwiki/. He's also got other interesting but not so relevant projects:He's also into Stack Overflow, Quora and Wikipedia editing. That's a cool dude. He's into in LessWrong it seems.

- Infinite Napkin.CC BY-SA mathematics infinite book: github.com/vEnhance/napkin/issues/77. Very similar type of content to what we want in this project!
- Stacks Project
Existing lecture notes by students:

- Cambridge Mathematics Lecture Notes by Dexter Chua (2014-2018)Comments:
Lecture note upload website:
- nexusnotes.com likely illegal reuploads of PDFs from teachers
- www.studocu.com/en-gb Paywall. PDF uploads. Unclear if simple teacher reuploads or actual novel notes.
- www.studydrive.net/
- Chinese GitHub repos. Some of these are very advanced in terms of content quantity and organizational quality! The Chinese are miles ahead in this area:
- github.com/PKUanonym/REKCARC-TSC-UHT Guidance for courses in Department of Computer Science and Technology, Tsinghua University. Chinese. Appears to try and store all past exams.

- github.com/chenyang1999/MyComputerCollegeCourses: TODO which univeresity
- github.com/elder-frog/OpenCourseCatalog: nothing to do with this project, but since I'm making a list, this dude is copying YouTube videos to Bilibili. And he's edgy anti-CCP on Twitter, what a legend.

That company's website must have gone into IP Purgatory, and could never be released as an open source website.As a student at the University of Michigan, he started a company that made lecture notes available free online, drawing a large audience of Midwestern college students and, soon enough, advertisers. At the height of the dotcom bubble, he dropped out of college, raised $10m from the venture firm Venrock and moved the company to Silicon Valley.His start-up drew interest from an acquirer that was planning to go public early in 2000. They closed the acquisition but missed their IPO window as the market plunged, and by August the company had filed for bankruptcy. Stock that Lawson and investors in his start-up received from the sale became worthless.He might actually be interested in donating to OurBigBook.com if it move forward now that he's a billionaire.
