By 1969, virtually every sizable city or college town in North America boasted at least one underground newspaper. During the peak years of the underground press phenomenon there were generally about 100 papers currently publishing at any given time. A UPS roster published in November 1966 listed 14 underground papers, 11 of them in the United States, two in England, and one in Canada. Within a few years the number had mushroomed. A 1971 roster, published in Abbie Hoffman's "Steal This Book", listed 271 UPS-affiliated papers; 11 were in Canada, 23 in Europe, and the remainder in the United States. According to historian John McMillian, writing in his 2010 book "Smoking Typewriters", the underground press' combined readership eventually reached into the millions.
