A catalog of reproductions and publications : color slides, books, catalogs, educational materials / National Gallery of Art. (OCLC #906962810)

It is said that metadata is a love note to the future, but sometimes that correspondence is vague and you end up in a “big laundry” situation.

I don’t know what “OCIR hole punch” means, but the years written on the shelf-list card and the label lead me to believe that we used to have 1969 volume, which was replaced with the 1971 version when it arrived, keeping the same SuDoc number. Lacking any other information, I cataloged the new volume on its own record with this SuDoc number.
