A study used the "Newsletter on Intellectual Freedom" to examine censorship cases in New Hampshire for the period 1966-1980. New Hampshire's reputation as a politically conservative state was upheld by the frequency of censorship incidents found, which was 1.5 times the national average in terms of population. Half the 15-year total of incidents occurred between 1973 and 1976. Although attacks were limited to educational institutions in the early 1970s, over the entire period they were evenly divided between educational and noneducational institutions. Most reported attacks took place in the cities and towns of the heavily populated southern part of the state, and originated from a variety of sources, including private citizens, parents, the police, and even librarians. In noneducational institutions, obscenity was the most frequent reason for complaints. More censorship attempts occurred in high schools than in any other educational institutions. For both kinds of institutions, a majority of censorship attempts were at least partially successful, although the success rate of 62% was lower than the national average. (JL)
