yes, I have worked in several museums that save all their exhibit materials and records of what was on exhibit. We had a file into which all the records were stored, and each object was recorded as having been on exhibit in their own specific file, even if it was a notation in the location file. We also kept paper copies of the exhibit labels and research that had been conducted. We may have filed the actual labels themselves, but that required a lot of space, so a paper copy was usually kept instead. Today, I used Past Perfect Museum software to record all our exhibits, so paper records have become obsolete. We also keep exhibit installation photographs.
