authoritative place where TeX related material and software can be found for download

CTAN (Comprehensive TeX Archive Network) is an online collection of open source LaTeX-related files and software (including Beamer).[1] In other words, this network is a LaTeX-only GitHub.[2]


CTAN is based in the United States,[3] United Kingdom[4] and Germany.[5] They also have several mirror sites (certified clones).[6] Mirror sites are needed in order to avoid access concentration. This effort helps the users to download files without fatal delay.
