have experimented with lithography – testing the resources of the medium to the utmost and producing what almost any experienced newspaperman would tell you was impossible... it is a creative dynamo whose influence will undoubtedly change the look of American publishing." In the period 1969–1970, a number of underground papers grew more militant and began to openly discuss armed revolution against the state, some going so far as to print manuals for bombing and urging their readers to arm themselves; this trend, however, soon fell silent after the rise and fall of the Weather Underground and the tragic shootings at Kent State. High school underground press During this period there was also a widespread underground press movement circulating unauthorized student-published tabloids and mimeographed sheets at hundreds of high schools around the U.S. (In 1968, a survey of 400 high schools in Southern California found that 52% reported student underground press activity in their school.) Most of these papers put out only a few issues, running off a few hundred copies of each and circulating them only at one local school, although there was one system-wide antiwar high school underground paper produced in New York in 1969 with a 10,000-copy press run. Houston's Little Red Schoolhouse, a citywide underground paper published by high school students, was founded in 1970. For a time in 1968–1969, the high school underground press had its own press services: FRED (run by C.

These services typically produced a weekly packet of articles and features mailed to subscribing papers around the country; HIPS reported 60 subscribing papers. G.I. underground press The G.I. underground press in America produced a few hundred titles during the Vietnam War, some produced by antiwar G.I. coffeehouses, and many of them small, crudely produced, low-circulation mimeographed "zines" written by a draftee editor opposed to the war and circulated locally off-base. Three or four G.I. underground papers had large-scale, national distribution of more than 20,000 copies, including thousands of copies mailed to G.I.'s overseas. These papers were produced with the support of civilian anti-war activists, and had to be disguised to be sent through the mail into Vietnam, where soldiers distributing or
