Non-mainstream media, often referred to as "alternative" or "underground" press publications, can be difficult to locate. Publications in this category include newspapers, magazines, newsletters, and other types of serial publications. These periodicals tend to be written from an acknowledged political perspective--for example, liberal or conservative--and they often promote a specific agenda, such a labor unionism, socialism, or communism. They might, however, report on news that is of interest to a specific community--often a marginalized one--without endorsing any defined ideology.
The digital collections below provide access to a wide selection of "alternative" publications relevant to this class. Find more alternative press material on our Alternative Press guide.
