Currently the catalogue number is visible next to the thumbnail. However, based on the document that the researcher is using, different unique identifiers are needed in order to find the artwork.

If the researcher is using an exhibition history report or publication report generated from CAT, they need the Artwork ID in order to identify the artworks.

If they are consulting the original exhibition catalogue, they need the exhibition checklist number or the reference number in order to identify the artwork (especially in cases where the artwork is not published with the same title as the artwork in CAT. In the screenshot, attached, it would be immensely helpful to see "cat. no. 151")
