I'm currently working on the copy-editing of the ____________ for a Museum of Ethnography exhibit that gives some fascinating insights into the archaeological process and the history of the items on display.
Apologies, the title isn't quite accurate, but it's the closest term that I could think of.
I'm looking for the word or term (if any exists) for explanatory texts that accompany artwork or museum pieces/collections.
I don't think "label" is appropriate, as these are usually quite short. I'm referring to texts of a paragraph or several paragraphs, and that provide context and background. They are found next to the exhibit in question, or (for longer texts) in an accompanying guidebook.
Thank you for any suggestions!
