In the Avery Library, prior to 2010, general museum collection catalogs are classed in N 1000 - N 1060. Many are also classed separately by subject. To find exhibition catalogs in CLIO, you can click on Advanced Search, and type “exhibition catalogs" (without quotes) as a subject field, then in the next box add either the museum name or a word in the title or the artist’s name, or a likely subject word you are looking for. Exhibition catalogs are separately classed by subject. Listed below are a few guides to finding citations to exhibition catalogs.
