OpenCourseCatalog

This repository is a curated catalog of university-level open courses that have been mirrored to Bilibili, a Chinese video platform. The curator created it because the original videos come from sites like YouTube that are blocked in mainland China, so domestic viewers cannot access them directly.

The catalog covers a wide range of academic subjects. Mathematics is the largest section, with courses on calculus, linear algebra, differential equations, probability, and more advanced topics like algebraic geometry and number theory. Computer science, physics, and other fields also appear. Most courses come from universities like MIT, Stanford, and Harvard, as well as international research institutes.

Each entry in the catalog shows the institution, the course name in both Chinese and English where available, and a link to the corresponding Bilibili playlist. Some courses carry subtitle notes: courses marked with Chinese and English characters have bilingual subtitles, those marked English-only have the original language subtitles, and some have no subtitles at all. The README notes that courses with inaccurate subtitles used YouTube's auto-generated captions, which may contain errors.

The repository itself contains no code. It is a markdown document functioning as a directory. Separate linked files cover courses from Taiwan-based institutions and courses originally on edX, which are maintained as separate sections because of different access or content moderation considerations.

If a course someone wants is not listed, the README invites users to open a GitHub issue with the course name in both Chinese and English, and the curator says they will look for it when time allows. The project is licensed under GPL v3 and carries an additional Anti-996 license, a Chinese open source license that prohibits use by employers who require excessive overtime hours.
