Sources

4,579 auction houses, read from their published results.

Records come from each house's own published results and, for the long tail of regional rooms, through the Invaluable and Artsy platforms. A platform is a route to a record, not a source of prices: every lot keeps the house that sold it and the date it sold.

Each record is kept once, keyed on the source and its lot number, so a sale read twice is still one sale. Unsold lots stay in the record.

Images

Copied, not linked.

Every lot image we can reach is stored on our own servers, so the record survives the source taking its page down. The rest have no image because the source published none, or we have not fetched it yet.

Method

The record, and only the record.

Collection runs around the clock on our own servers. Each run reads a house's published results, keeps the lot as the house described it, and files it under the sale date and the artist name the house gave. Nothing is rewritten; when a name is cleaned for matching, the original stays on the record.

Prices are not shown on this page. They appear where they are read against something: a collector's own works, or the movers on Market Pulse.
