The Archive of Formal Proofs

 

The Archive of Formal Proofs is a collection of proof libraries, examples, and larger scientific developments, mechanically checked in the theorem prover Isabelle. It is organized in the way of a scientific journal and has an ISSN: 2150-914x. Submissions are refereed. The preferred citation style is available [here]. A development version of the archive is available as well.
