panOpticon is an online information management system
specially designed to help provenance researchers
process and share the varieties of data it takes
to produce a catalogue raisonné

Our software follows cataloging best practices as recommended by leading members of the Catalogue Raisonné Scholars Association we refer to the Visual Resources Association guidelines for describing cultural works and images we use The Chicago Manual of Style as a guide in formatting texts.

And we continuously work with professionals in the industry to improve and update our product features and protocols.

“One of our challenges is to create a complex online reference that can cover the many aspects of Lichtenstein’s work. It was sometimes rather difficult to establish a clear and integrated architecture, but with the help of our panOpticon database we are making great progress.”
 — Roy Lichtenstein Catalogue Raisonné Project
