Metamath is a formal language and an associated computer program (a proof checker) for archiving, verifying, and studying mathematical proofs. Several databases of proved theorems have been developed using Metamath covering standard results in logic, set theory, number theory, algebra, topology and analysis, among others. This project is the first one of its kind that allows for interactive browsing of its formalized theorems database in the form of an ordinary website.
