One of the most popular questions we receive through the Library’s Ask a Librarian service is if we have a list of every image in the public domain. While it’s impossible to create such a list, we have found a way to guide people to images that are free to use and reuse. The Library’s Free to Use and Reuse sets contain images that are either in the public domain, have no known copyright, or have been cleared by the copyright owner for public use.
