Almost every bibliographic record for an exhibition catalog includes the subject word Exhibitions:
Renoir, Auguste, 1841-1919 -- Exhibitions
Sisley, Alfred, 1839-1899 -- Exhibitions
Caillebotte, Gustave, 1848-1894 -- Exhibitions
Impressionism (Art) -- France -- Exhibitions
Still-life painting -- 19th century -- Exhibitions
In addition, almost every bibliographic record for an exhibition catalog has a description of the exhibition--and this description includes the searchable word exhibition:
Published in conjunction with the exhibition held Sept. 16, 1994-Jan. 9, 1995 at the Galeries Nationales du Grand Palais, Paris; Feb. 18-May 28, 1995 at the Art Institute of Chicago, and June 22-Sept. 10, 1995 at the Los Angeles County Museum of Art.
Catalog of an exhibition held at the Musee des Beaux-Arts, Lyon, Oct. 10, 2002-Jan. 6, 2003.
To find an exhibition catalog focused on an artist or a particular topic, perform a keyword search that includes the artist's name (last is usually sufficient) or the topic word or words and the search word exhibition* -- this truncation (symbol: *) will search for both the descriptive word exhibition and the subject word exhibitions.
Caveat: do not use the word exhibit (or exhibits) in your search--you might get a few results, but exhibit or exhibits is not used consistently in bibliographic records for exhibition catalogs.
