deliver your content

With many of the features you’re looking for in a public-facing online catalogue already built into our back-end, you have huge advantages when it comes time to publish.

When you are ready to publish you’ll have several options:

We can design a site for you – the same knowledge we put into our cataloging software we put into our websites. You determine the look and the feel and decide on functionality.

Or, we can plug into your existing site – in which case we’ll work with your designer to “wrap” your catalog.

Or, you can generate text files to incorporate into design for print.


  • Our back-end is structured to deliver all the requisite core information linked together following cataloging best practices (see cataloging). You can choose what to publish and how to display it, but the entire framework is there.
  • Many of our software’s extras (commentaries, keywords, supplemental tables) let you create enriched add-ons (animated and interactive elements) that draw from deeper levels of the database.
  • Data is automatically formatted and styled by the system, so the transition to the web is flawless.
  • Your back-end is joined to your site, so you publish from your tool. You can compare your data to your site files. Publish and update your online publication whenever you wish.
  • Your content can also be purposed for print or ePublishing.


Paul Cézanne. La Montagne Sainte-Victoire vue du chemin de Valcros,

The Paintings of Paul Cézanne takes Cézanne scholarship in new directions, while all the known paintings are being made available in color for the first time. The catalogue is of benefit to students, scholars, curators, collectors, galleries, and auction houses as well as anyone who wants to learn more about one of the most revered and influential painters of the late 19th and early 20th centuries.

“The work panOpticon did for us in setting up a database for Paul Cézanne was brilliant. They clearly understand the concept of a catalogue raisonné and their system is easy to use, flexible in its application, and amazingly comprehensive. We are thrilled with the final product and, in fact, would probably not have been able to produce this catalogue at all without their help.”
– David Nash, co-author of The Paintings of Paul Cézanne: An online catalogue raisonné under the direction of Walter Feilchenfeldt, Jayne Warman and David Nash

The Edwin Dickinson Catalogue Raisonné
The American painter Edwin Dickinson (1891-1978) was born in Seneca Falls, New York, studied with William Merritt Chase and Charles W. Hawthorne, and spent most of his working life on Cape Cod and in New York City.

Helen Dickinson Baldwin, the artist’s daughter and author of the new online Edwin Dickinson Catalogue Raisonné writes,

“Father’s studios were always filled with a tremendous variety of artifacts. Broken china, drapes, and furniture from his grandparents’ house mingled with things that in some way attracted him from the town dump. One of his finds, a single old boot, he placed in a large glass lantern box and painted it into his Two Figures II (1922-1924), now hanging in the Metropolitan. The old bent harpoon and the death mask of Beethoven seen here were among the things he kept all of his life.

“Though others might consider his studios cluttered and crowded, for my father every object had an association which was for him nourishing, even inspiring.” [read more]

The design and production of the Edwin Dickinson Catalogue Raisonné is the result of a cooperative venture between Helen’s husband and designer Robert Baldwin, and the creative team at panOpticon who employed their innovative technical and design expertise in developing the software and creating the website.



The John F. Folinsbee Catalogue Raisonné
Research Director and Editor, Kirsten M. Jensen was asked to head up the Folinsbee Catalogue Raisonné project in 2004. “The idea to make the catalogue an online venture, rather than a print publication, intrigued me for the technical challenges it presented as well as the possibilities for making Folinsbee’s work more widely accessible—and sooner. Typical catalogues raisonnés take years before they are published, are expensive to produce and purchase, and are often outdated not long after ink hits the paper’s surface. The Web, however, provided us with the opportunity to change that paradigm, to make the catalogue of Folinsbee’s oeuvre immediately available to the public in a form that would be as current as possible.”

The American landscape painter John Fulton Folinsbee (1892–1972) was best known for his impressionist scenes of the factories, quarries, bridges, and canals along the Delaware River. With little time or need for “isms,” Folinsbee filtered a broad array of stylistic influences, both traditional and contemporary, into a method of painting that was uniquely his own. It is the hope of the Trust that the online Catalogue Raisonné will foster a greater appreciation for Folinsbee’s work and re-place him in the canon of twentieth-century American art.

Among the many unusual features that gives the John F. Folinsbee Catalogue Raisonné special appeal is the number of instances where the user can view groups of related works, like the cloth-bound Sketchbook (1926) that Folinsbee filled on his trip through France. Select any of the thumbnails at the bottom of the page and click through a slideshow of all forty-three drawings.


The Jack Tworkov Catalogue Raisonné
Editor Jason Andrew worked with us to integrate nearly eight years of research seamlessly into the new Catalogue Raisonné housed within the framework of the Jack Tworkov website. The site was designed by Goingoffscript.

Jack Tworkov (1900-1982) was a founding member of the New York School and is regarded as one of the prominent figures, along with Willem de Kooning, Philip Guston, Jackson Pollock, and Franz Kline, whose gestural paintings of the 1950s formed the basis for the abstract expressionist movement in America. With a career spanning five-decades, this new website highlights Tworkov’s historic presence and significant contribution to American Art of the 20th Century. In 2009 the artist’s writings were compiled and published in the book Extreme of the Middle: Writings of Jack Tworkov by Yale University Press.

The Tworkov Catalogue editor Jason Andrew has been active with the Estate since 2004 and was responsible for organizing and curating the first comprehensive retrospective exhibition of the artist’s work ever held in New York City in 2009. The project also benefits from the participation of the artist’s daughters, Hermine Ford and Helen Tworkov.

The first stage of the Tworkov Catalogue Raisonné Project features works on canvas with currently over 300 works online and growing. The goal is to eventually include all works made by the artist, including paintings and works on paper. The site will eventually add correspondence, audio and video recordings, and other documentation that will contribute to the definitive statement on Jack Tworkov.

The launch coincided with the 30th anniversary of the artist’s passing in 1982.
