CTAN (Comprehensive TeX Archive Network)

The Comprehensive TeX Archive Network (CTAN) is a vast online repository that centrally stores and distributes TeX-related software, packages, and documentation. TeX is a typesetting system widely used for producing scientific and technical documents. CTAN serves as the primary resource for users, developers, and publishers to access the latest tools, fonts, and extensions for TeX, ensuring consistency and ease of access for the global community. It functions much like a specialized library, supporting the creation of high-quality, complex documents across various disciplines.
