Newspapers can also be a great place to find coverage of media and reviews. The Library subscribes to a number of different newspaper databases. Some of these databases are just for a single newspaper (ex: The New York Times), while others have a lot of different newspapers in one databases (ex: Global Newsstream).

Besides film streaming databases, the Library also has a large collection of DVDs. You can find DVDs through Library Search (the big search bar on the Library's website) or by browsing the collection in-person on the 3rd floor of the Multi-Tier Stacks (the Mudd side of the building).
