“I can’t imagine finding anyone more qualified or capable of creating an online catalogue raisonné than panOpticon. Someone else might have the programming skills, but the panOpticon staff combines superior programming knowledge and an ability to create web page designs that are attractive and user-friendly with a profound understanding of what a catalogue raisonné is and how it should function for a wide range of audiences.
“panOpticon did far more than create a Cassatt catalogue raisonné site that is a pleasure to use—they were also partners in conceptualizing a site that suits our particular needs and transforms the catalogue raisonné into a twenty-first century scholarly tool.”

“The work you have done for us on the Mary Cassatt Catalogue Raisonné has been beyond our expectations. You and your crew have been at all times professional, timely, and thoughtful. But of greater importance to the project, your creative guidance has made the website special and in all ways brilliant. I recommend your work without reservation.”

“One of our challenges is to create a complex online reference tool that can cover the many aspects of Lichtenstein’s work – sometimes it is rather difficult to establish a clear and integrated architecture. But with the help of our panOpticon database we are making great progress.

“The designers of the panOpticon information management system clearly understand the complexities of a catalogue raisonné. Their IMS conveniently organizes the rich levels of detail and documentation required by scholars, and it presents the information in formats that appeal also to general audiences. We consider it a strong and flexible foundation for the preservation and presentation of our work. The panOpticon support staff is always responsive to our questions and needs.”

“The work panOpticon did for us in setting up a database for our catalogue raisonné of Paul Cézanne was brilliant. They clearly understand the concept of a catalogue raisonné and the system they have set up for us is easy to understand, 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. They have a clear understanding of what information will be of interest to scholars and general readers and have a sensitivity toward Cézanne’s work and existing scholarship which has greatly impressed me.”

“Our primary goal with the Catalogue Raisonné of Works on Canvas by Jack Tworkov was to make our extensive research publicly accessible and offer a forum for a resurgence of interest in the work of one of America’s great Abstract Expressionists. panOpticon’s state-of-the-art software converted years of research into a precise and easy-to-navigate program. I was astonished by how quickly and efficiently our research was transformed into a concise design, professional presentation, and manageable system. This is where panOpticon’s online software outstrips by far any other on the market.”

“The Sam Francis Foundation joins the other testimonials with our praise of panOpticon’s system. Using the database they have created has made our documentation and research immensely organized and extremely useful on a daily basis due to its layered search and linking capabilities. We have been working with them for a few years in the compilation of the Sam Francis catalogue raisonné of unique works on paper, and can’t imagine a more perfect system for this process.
“The ease with which we can input the data, upload images, create lists and notes as part of our daily research has allowed us to expand our archival database in so many ways. We are looking forward to launching the information online, another incredible aspect of the system that we are so excited about. Not only is the system intuitive and easy to access and learn, the staff at panOpticon are always willing to tweak the categories and develop ways for us to input data to fit our specific needs. And, if there are ever any questions they are so proficient and quick in their responses and assistance.
“It is a dream tool—perfect for the intensive amount of information one must organize in compiling catalogues. We highly recommend panOpticon and their team.”

“The Estate of David Smith is currently using panOpticon for our catalogue raisonné and archives databases and for more general inventory purposes.
“Although we don’t plan to publish the David Smith Sculpture catalogue raisonné on line (it will be published as a three-volume book, by Yale University Press), we may decide post-publication to turn on the public-facing features of our panOpticon database in order to share updates and new finds.
“We’ve found panOpticon to be a remarkably good partner, working with us to migrate the data from our old system, and willing to add features and customize aspects of the basic panOpticon system so we could make it work well for our particular needs.”

John F. Folinsbee. Canal and River,

“We could not be happier with panOpticon’s incredibly intuitive and easy to use software for our catalogue raisonné. The transition of our data from our old database was practically seamless, and panOpticon responded to questions and concerns quickly. Both the public and the administrative pages are professional in design and presentation, and we are very excited to launch our new site in 2013.”

Fitz Henry Lane, Gloucester Harbor from Rocky Neck 1844

“The Fitz Henry Lane Catalogue Raisonné Project at the Cape Ann Museum has worked with panOpticon from the project’s inception over a year ago. Our project’s core need was a flexible, fully searchable database of all of Lane’s work incorporating all the proper catalogue raisonné style protocols. In addition we wanted to be able to include far more historical and reference information than the traditional catalogue raisonne. After looking at numerous cataloging database software solutions, it became clear that the “one size fits all” architecture of commercial database software was going to need extensive adaptation for our needs, far beyond the expertise or budget of our project.
“We were introduced to panOpticon through their online Mary Cassatt Catalogue Raisonné project that was still in process. It was immediately apparent that they had confronted and solved all the myriad problems associated with style protocols and had created extraordinary keyword search abilities that opened up numerous new avenues for understanding an artist’s work. Perhaps most importantly, the software has a user interface that automatically applies correct style and punctuation to all entries.
“They are very easy to work with, prompt and responsible in follow through on all issues. The training is straightforward and the software itself can answer most questions itself going forward. Most importantly, they understand the field of art scholarship as only an insider can. I can’t imagine what it would be like to try to explain the nuances of style and organization necessary to a catalogue raisonné to an ordinary software programmer or consultant. The amount of time and effort we have saved in the start-up phase alone is incalculable and the ongoing efficiency of the data input and organization continues to allow us to focus our resources on the core research.”

“panOpticon has developed and implemented databases for both the Mary Cassatt and John Singer Sargent Catalogue Raisonne projects sponsored by Adelson Galleries. I have been personally involved with the Sargent catalogue raisonné and the various incarnations of the database since the late 1980s. Last week we sat down to view our new Sargent database and we were thrilled with the work that the team has done. They have a global understanding of compilation, editing, sorting, and cross-referencing requirements which made it very easy to discuss our particular needs. They were flexible in their approach to the material and changes or re-considerations we asked for were never problematic. Aside from the obvious complexities that are inherent in developing a new program (as well as the integration of old database files), the team at panOpticon has created a visually organized and intuitive database that we expect to use for many years to come. I would recommend them without reservation.”

Paul Cézanne. Les Joueurs de cartes,

“I have the distinct pleasure in recommending panOpticon as superb designers of online catalogues raisonnés. I first became aware of their work when given a preview of the Mary Cassatt Catalogue Raisonné, sponsored by New York’s Adelson Gallery—I was very impressed with the comprehensiveness, scholarship, and elegance of the program and website. It is unique in that regard.
“Fortunately, Mitchell-Innes & Nash agreed to hire panOpticon to design a similar online catalogue for the French painter, Paul Cézanne. It is exactly the kind of program that we have been looking for.
“The panOpticon team combines the professionalism, knowledge and understanding of the scholarship required to effectuate such a substantial project, while providing a user-friendly design for those who are new to this kind of online format. I would add that they have been very accommodating from the beginning of our relationship and have gone out of their way to respond to our myriad questions and concerns.”
