“The panOpticon staff combines superior programming knowledge with a profound understanding of what a catalogue raisonné is and how it should function for a wide range of audiences.

“panOpticon has done far more than create an online system that suits our needs, they have transformed the catalogue raisonné into a 21st Century process.”

Pamela A. Ivinski

Mary Cassatt Catalogue Raisonné Project



The Artist Estate: A Handbook for Artists, Executors, and Heirs is a must read for anyone with a stake in the art industry. Edited by Loretta Würtenberger, co-founder of The Institute for Artists’ Estates in Berlin, this invaluable book has a chapter entirely devoted to the catalogue raisonné. In it she says —

Today, a catalogue raisonné should be digitized; it almost goes without saying that online databases can be expanded and updated easily. Moreover, the scope of the online catalogue raisonné should encompass the following:

1. Links to internal archival material
2. Links to documentation such as checklists and exhibition photographs
3. The integration of video and audio materials
4. The possibility of incorporating negative or inconclusive results, so that the limits of previous research are well understood
5. Links to external sources such as archival holdings and press articles or other publications, as well as public search engines and databases.”
