To find a movie in the catalog, start at the catalog, cat.pratt.edu. Click on the Advanced tab, and narrow your search by Material Type. By holding the Shift or Control key, you can select more than one material type, so as to search Blu-ray AND VHS AND DVD AND 16 mm. Enter your search term as a keyword ("Any Field"), title, author, or subject.
This will return the following results, which show their Location (1) in MMS Media (basement floor of the Brooklyn campus library), their Material Type (2) as film, and their Status (3) as Available or Library Use Only. A keyword search for a term like Kurosawa will give results that include movies BY him as well as movies ABOUT him, which can be useful to your research.
