征集范畴论最新讲义及官方免费在线书籍信息

Hey everyone,

I’ve been curating a category theory resource page for some time now, and it currently features around 20 sets of specialized lecture notes and 16 well-regarded free official books. With thousands of monthly visits, it’s proven to be a go-to spot for folks in the community looking for quality materials.

My goal is to keep this page maintained and updated as a way to give back—while I don’t plan to cover every single resource out there, I want to ensure it’s stocked with the best of the best. I recently added a few new links and verified that all existing ones are still active, but since I’m not a professional category theory researcher, I’m turning to you all for help!

If you’re a category theory educator, industry practitioner, or even a student who’s recently taken a course on the topic, I’d appreciate your input:

• Latest lecture notes: Share any recent, high-quality lecture note sets you’ve come across
• Free official online books: Point me to any free, officially published online books that aren’t already listed
• Maintenance tips: Offer advice on how to keep this resource organized, relevant, and useful (like curation guidelines, categorization strategies, etc.)

Thanks so much for taking the time to contribute—your help will make this resource even more valuable for the entire category theory community!
