Reports

It presents the size of the market, the segments, the regions and the year's largest sales. It distinguishes public sales, declared private transactions and fairs. A methodological section explains the origin of the data and its limits.

The report also offers a thematic chapter, different each year: digital market, tribal art, taxation or insurance.

It traces the year's activity: registrations of works, certifications, disputes resolved, officers trained, international operations. It includes the Organisation's accounts and the up-to-date list of Member States.

One chapter is devoted to the priorities for the following year, validated by the General Assembly.

The tables of both reports are distributed as CSV, with a dictionary of variables. The market series go back to 2010. Each file states the extraction date and the revisions made since publication.

Revised figures are flagged in an errata note. Readers should always cite the latest version available.

The data come from declarations by approved auction houses, customs administrations, the Organisation's registries and surveys of galleries. Systematic cross-checking limits double counting.

Estimates are expressly identified. Margins of uncertainty appear in the methodological annex.

Alongside the two main reports, thematic notes of twenty to forty pages address a specific subject: restitution, arbitration, digital certification. They are written by the directorates concerned.

These notes are published as they are ready and announced in the monthly newsletter.
