Methodology

What a record is

A record is one page for one work of art. It states what the work is, where it is now, every owner we can document, where it has been exhibited, what has been written about it, and what it has made at auction. It is not an essay and it is not a biography of the artist.

Source hierarchy

We prefer, in order: the holding institution's own record; catalogues raisonnes; period documents such as wills, inventories and dealer stockbooks; auction catalogues; scholarly literature; contemporary press. A claim that rests only on press is marked as such.

How certainty is marked

Every link in a provenance chain is graded. Documented means a cited source supports it. Disputed means the identification is argued but not established. Unknown means we have no owner for that span and have not bridged it. We do not smooth a gap into a narrative.

The evidence gate

A record is published only when it carries at least three documented provenance events, at least two cited sources, and written summary prose. Records below that bar remain unpublished and carry a noindex header. They still exist in the corpus.

AI assistance

We use AI tools to help find, compile and cross-check sources. Every published record and article is reviewed by a named human editor before it appears, and every factual claim is tied to a source a human has checked. AI is not used to generate images of real works of art.

Images

Works in the public domain are reproduced and credited to the holding institution. Works still in copyright are not reproduced; we link to the rights holder instead. We never generate or simulate an image of a real work of art.

Corrections

We correct openly. Every record carries a change log and a last-verified date. Write to [email protected] with the correction and, if you can, the source.
