## What it is
A curated catalog of open university courses (MIT, Stanford, ICTP, etc.) that have been re-uploaded to Bilibili for viewers in China. It organizes links by subject such as mathematics, analysis, and algebra, with notes on subtitle availability.

## Use cases
- find free university math lectures with Chinese subtitles
- watch MIT OpenCourseWare videos accessible in China
- find linear algebra and calculus course recordings on Bilibili
- discover mirrored edX and YouTube lectures
- look up open courses by topic like analysis or algebra

## When to choose
- you are in mainland China and cannot access YouTube or edX directly
- you want a curated, subject-organized index of open course videos
- you need to know which lectures have Chinese or English subtitles

## When to avoid
- you need the original course materials, assignments, or certificates
- you can access YouTube and edX directly and prefer official sources
- you need recently added courses, as the catalog is no longer actively updated
