The Colby name and various logotypes are federally registered service marks, and with the exception of the several regular student publications approved by the College and the Student Government Association, the College exercises editorial control in the matter of content, taste, and style of its own publications, advertisements, and other products. This protection, including the right to delete or remove, extends to all other materials, commercial goods, clothing and apparel, posters, and other advertising produced by others that imply College endorsement.
