This searchable bibliographic database collects the annual bibliographies on ancient athletics published in the journal Nikephoros beginning in 1986. It includes books, articles, and other scholarly resources in multiple languages. The database can be searched by author, title, publication and keyword (in English, and adding keywords to records older than 2010 is still in progress.) You can also contribute by adding keywords! The current maintainers welcome additions, including citations from before 1986.
