Videos should be weeded just like any other format if not perhaps more so. The Library of Congress does not catalog videos as a matter of course consequently, video cataloging is among the most fluid. Video cataloging does, however, follow many motion picture rules. The chief source for a video's title is the credit screens. If you are unable to preview the video, clearly state where the title came from in a source of title note.
Videos are normally works of mixed responsibility, and have title, rather than author, main entry.
The statement of responsibility usually includes the director, producer, and writer, following Library of Congress practice for motion pictures. Varying titles from the label or packaging should be recorded in MARC tag 246. Added entries are usually only made for director, producer, writer, and actors, but exceptions can be made if the person is important to the production. Summary notes are very important in video cataloging because a patron cannot browse a video like one can open a book. While videos still require different treatment than print materials, the processes associated with the selection, acquiring, cataloging, and maintaining video material in libraries can be mainstreamed into library workflows.
