  Non-classical logics are used in a wide spectrum of disciplines, including
artificial intelligence, computer science, mathematics, and philosophy. The
de-facto standard infrastructure for automated theorem proving, the TPTP World,
currently supports only classical logics. Similar standards for non-classical
logic reasoning do not exist (yet). This hampers practical development of
reasoning systems, and limits their interoperability and application. This
paper describes the latest extension of the TPTP World, which provides
languages and infrastructure for reasoning in non-classical logics. The
extensions integrate seamlessly with the existing TPTP World.
