# AoPS Wiki:Resources

This is a place for various user-created content compiled from the forums. This information is already on the forums, but is compiled by users into easy-to-access PDF format. The ultimate goal of this page is to archive user-created content, not old contest PDFs. However, until the Contests section is fully operational on AoPS, this page will continue to link to old contests, such as the AIME below.
