I'm trying to build out my own personal library that efficiently replicates as much knowledge as I can fit in there. I know a lot of people approach this from many different directions. Mirroring libgen or scihub is too big a project for me right now, so I'd like to have textbooks that would mostly recreate any degree you could get at most large US universities. I expect this would end up being around ~1000 textbooks and handbooks total by the end of it.
I started trying to map out how I would do this and it is a lot of work. Collating syllabi and book recommendations with prerequisites is a lot of work, especially given the number of departments in a typical university. OpenSyllabus is great but it not clear if their API would be able to help me. I've contacted them about pricing for self-learners but they haven't gotten back to me.
There are lots of piecemeal examples of what I want, such as this math roadmap but I don't know if anyone has aggregated something approximating what I want.
Does anyone know if something like this exists? If not I'll start building it out, but it's going to take awhile.
