The WPI research teams are working to prepare new and updated catalogue raisonné and digital corpus projects that document the decisions of our expertise committees. If you would like a work to be considered for one of these digital publications, please visit our “Submit a Request” page for more information:

• Romare Bearden
• Paul Gauguin
• Eva Gonzalès
• Édouard Manet
• Albert Marquet
• Claude Monet
• Camille Pissarro: Paintings, Pastels, and Gouaches
• Odilon Redon
• Pierre-Auguste Renoir: Paintings, Drawings, and Pastels
• Kees van Dongen: Paintings
• Maurice de Vlaminck
• Tom Wesselmann

With the exception of any decisions made by the Renoir Committee before 2003 and any decisions made by the Van Dongen Committee at the Wildenstein Institute, the works that were given “Attestations of Inclusion” by the Wildenstein Institute will be included in the relevant forthcoming WPI publications. However, the WPI reserves the right to reconsider any previous decision.

No. The WPI does not authenticate works of art nor do we make any representation regarding the value of works of art. 

From time to time, the WPI will publish printed materials related to the artists and art historical periods under our study. All forthcoming catalogue raisonné projects will only be published online.

No. The WPI does not seize, destroy, or physically alter any work of art submitted for examination.

If you would like to know if a work was ever issued an Attestation of Inclusion from the Wildenstein Institute, you must submit an Archival Inquiry. We can check to see if we have a file on the work and whether it was issued a letter of inclusion or non-inclusion.

No. The WPI does not re-issue letters that have been lost. If you would like a written Letter of Determination from the WPI, you will need to submit a Request for Research and Inclusion.

No. The WPI is not in possession of any of the Wildenstein gallery records.

If you would like to receive a Letter of Determination from the WPI, you will need to submit a Request for Research and Inclusion.

Following the research and in-person examination of a work of art by scholars at a committee meeting, you will receive a letter from the WPI indicating that:

• the work will be included in the WPI Digital Catalogue; or
• the work will not be included in the WPI Digital Catalogue; or
• no determination about the work can be made

If the work is to be included in a forthcoming Catalogue, the WPI may also provide information on the provenance, as well as relevant exhibition and bibliographic citations, as a courtesy to you. If the work will not be included, the WPI reserves the right to provide no further comment. 

Committees meet periodically throughout the year on an as-needed basis in either Paris or New York. You will be notified of the location and date of a forthcoming committee meeting after we receive your Request for Inclusion.

The WPI can only fulfill Archival Inquiries for works on which we maintain research dossiers. We are not able to answer requests that do not relate to a specific work of art for which we maintain a research dossier.

If you send us an Archival Inquiry, we can verify if a work of art was previously recorded in the Archives and provide a summary of the information contained in the archival dossier. Since these dossiers contain information that may have been compiled by third-party institutions, we cannot make any representations or warranties about the content or accuracy of the information contained therein. This service is subject to a non-refundable fee of $550, plus NY state sales tax. You can submit your request on our Archival Inquiry page. However, if you would like additional information on a work of art that would require our staff to do research that is not included in a historic dossier, you must submit a Request for Research and Inclusion. 

We do not perform bespoke research on individual works. The WPI is unable to perform any new research unless a Request for Research and Inclusion has been submitted.

Yes. In December 2022, the WPI created a new Maurice de Vlaminck committee to examine requests for inclusion in the artist’s catalogue raisonné. Our forthcoming digital publication will consist of works given Attestations of Inclusion by the Wildenstein Institute and WPI between 1992 to 2018. However, the WPI reserves the right to reconsider a previous decision. 

If you would like to submit a work for review by the Comité Vlaminck, you may do so here.

We will not provide any refunds if our staff have already begun work on a request. However, the WPI will provide a refund, less any applicable processing fees, for an Archival Inquiry that is exchanged for a Request for Research and Inclusion for the same work of art. All refunds are subject to processing fees. No other refunds will be provided for services rendered.
