The Internet, Public Libraries, and the Digital Divide

Virtually every public library in the United States provides public access Internet computers as a role central to its mission. This article addresses the issue of why the Internet matters for public libraries, both in terms of impacts on the general public, particularly the digitally disadvantaged (part one of the article) and impacts on libraries themselves (part two of the article). Each part of this report begins with an extensive literature review, followed by a data analysis section. In part one, the author uses the 2000 United States Census dataset to evaluate library efforts to bridge the digital divide, by analyzing differences in the growth of public terminals in library systems serving counties with different levels of household income, households in poverty, non-white households, and non-English-speaking households. The analysis finds no disparity in the number of public computers available in areas with high and low incomes but finds a significant-and widening-disparity in the number of computers available in areas with a higher versus lower percentage of non-white and non-English-speaking households. In part two of the report, the author uses a random effects linear regression model to estimate the effects of Internet access on library usage. This analysis finds that having Internet terminals (versus having no Internet terminals) has a significant positive effect on a library's visits and reference transactions, but not on a library's circulation. An increase in the number of Internet terminals has no significant effect, positive or negative, on visits, reference transactions, or circulation.
