This collection contains underground newspapers originally compiled by the Underground Press Syndicate, mostly published in the U.S., but also from Canada, Latin America, and Europe. Individual titles cataloged separately.

The initial compilation of this fiche and microfilm set covered titles from 1961 to 1972. Since then, an annual update has been issued with additional holdings and titles.

CRL holds the microfiche edition (1961-1988) as well as the microfilm collection (1971/72-1997).

This set supplements UMI’s Underground newspaper collection by adding missing issues and other titles from the holdings in the Hoover Institution on War, Revolution, and Peace.

This set complements the Underground and Alternative Press and The Left in Britain collections by offering contemporary grass-roots and radical literature published in Britain.
