This recently released report from the National Coalition Against Censorship (NCAC) reports on their research about products and software used to filter Internet content. Over the spring and summer, NCAC's Free Expression Policy Project reviewed all of the studies and tests it could find covering the nineteen most common Internet filtering tools. This report, summarizing the review, gives a general introduction and results for each of the nineteen products as well as a bibliography and appendices covering blocked sites by subject and blocking categories. In the main, NCAC finds that the technology used in blocking is too indiscriminate because of its dependance, to at least some degree, on mechanized means of filtering. NCAC suggests that "Ultimately, less censorial approaches such as media literacy, sexuality education, and Internet acceptable-use training may be better policy choices than Internet filters."
