The catalog is the place to search for BOOKS, JOURNALS, and DATABASES. (Use databases to search for individual articles.)
If you're looking for a specific journal title, start by selecting Advanced Search, then pick the Title field, and then select Journal/Periodical for the Material Type.
Searching this way will put the journal titles with your keyword (e.g., "Film") at the top of the results list.
Most databases use a special character (wild card) to search all the possible words for a given suffix.
Web of Science uses *; the library catalog uses * for 1-5 characters and ** for unlimited characters.
