Manuscript Preparation, Copyediting, and Proofreading
Q. How do you create a bibliographic entry for a visit to a museum?
A. Bibliographies normally list citations of published works. If you want to refer to a museum in your paper (or a pizza or a tattoo or any of the other items that writers like to cite these days), just describe it in the text along with a place and date (if you know them) and resist forcing the information into citation style.
