This presentation covers research on software authorship and citation, which we carried out between July and September 2019. We examined codes authored by three or fewer people (“short author list” codes) and codes authored by institutional teams, to determine how many codes in the ASCL can be attributed to one of these categories. Utilizing ADS data, we measured the number of citations per authorship category. We carried out further research to determine whether we could infer software usage and code usage statistics from the number of citations to code description papers. Our research shows that citations to code description papers are not a reliable proxy for software usage.
