I would like to address the issue that the exhibitor and the venue are often separate entities. For example, there is usually an organization or the artist arranging the exhibition, while the venue is a separate physical location. In Finland, for instance, the organizer was often the Finnish Art Society, but the exhibition might take place in a library or, later, in the Finnish National Gallery’s Ateneum building, once it was finally built and opened in 1888. In this case, the library serves as the venue, but it is not the exhibitor. The venue itself is not the most important information; the organizer is. I hope this makes sense - thank you!
