Films (and books about films) have subject headings assigned to them. Many film genres can be searched by subject. Go to infoLINK, the Libraries’ catalog and do a subject search under the subject heading. If you don’t know the subject heading, try a keyword search. The following are some sample subject headings for different types of films.
Adventure Films
Detective and Mystery Films
Documentary Films
Experimental Films
Film Noir
Musical Films
Western Films
If you just need a list of films that cover various subjects, try the Internet Movie Database and use the Plots or Keywords option under the Search the IMDB box.
