This guide is not intended to be a comprehensive list of all film studies resources, free or otherwise. To find more recommended sources for journals, databases, books, primary sources, data, and reference materials, I recommend consulting the many wonderful online research guides on film, television, and media studies provided by academic librarians.
To easily find these guides, do an advanced Google search with the following keywords:
film studies library site:edu
This will limit your results to university websites, which often use the 'edu' domain.
