The Archive of Formal Proofs (AFP) is an online repository of formal proofs for the Isabelle proof assistant. It serves as a central location for publishing, discovering, and viewing libraries of proofs. We conducted an online survey in November 2020 to assess the suitability of the website. In this report, we present and discuss the results, which showed that long-term users of the website are generally satisfied with the AFP but that there are a number of areas, such as navigation, search and script browsing, that need improvement.
