This paper presents findings from interviews conducted with editors of catalogue raisonné projects in various stages of development combined with the author’s work on the Catalogue Raisonné of the Drawings of Jasper Johns. A summary is presented of the common mission and challenges in preparing the catalogue raisonné as well as the considerations for, and benefits of, publishing online. The result is a concise reference tool of best practices and suggestions for future catalogues raisonnés and online catalogue projects, including features available if publishing online; staff recommendations; workflow; database options; data migration; research; storage of research assets; and long-term maintenance.
