The UCSB Library is committed to making a reasonable effort to identify the origin and creators of all works on display, and to attribute these works accordingly, per standard practices in the library field (excerpted below).
“Full attribution, in a form satisfactory to scholars in the field, should be provided for each work included or excerpted in an exhibit, to the extent it can be determined with reasonable effort.” Association of Research Libraries Code of Best Practices in Fair Use
“Institutional practices must be designed so that exhibitions, publications, and public information are presented honestly and objectively. The stated origin of an item or attribution of a work must reflect thorough investigation and must promptly be changed in the event of accurate challenge. Library exhibitions and publications routinely address a wide variety of social, political, artistic, or scientific issues. Exhibitions from whatever source and on any subject can be appropriate, if approached objectively and without prejudice.” Standards for Ethical Conduct for Rare Book, Manuscript, and Special Collections Librarians, with Guidelines for Institutional Practice in Support of the Standards, 2d edition, 1992
