lib-pku/libpku

libpku is a community-maintained archive of course materials for students at Peking University (one of China's most prestigious universities, often abbreviated PKU). The repository collects exam papers, lecture notes, textbooks, reference sheets (called "A4 papers"), and other study resources for courses across the university, organized by department and course name. The goal, as described in the README (written in Chinese), is to make information that was previously scattered across private chat groups and passed informally from student to student publicly available and easy to find, so future students do not have to spend time hunting for resources that previous students already compiled. This is not software you install or run. It is a document collection and reference repository. The primary language listed is TeX because many academic documents, especially in mathematics and computer science, are typeset in LaTeX (a document preparation system used widely in academia). The materials themselves are downloadable via the project's companion website at lib-pku.github.io. Someone would use this if they are a student at Peking University looking for past exam papers or course notes, or a researcher interested in what topics are covered in PKU's curriculum. The README notes that copyrights remain with original authors and the repository does not charge for or profit from the materials. The README is written entirely in Chinese.
