Mixed method research design employed by the U.S. IMPACT studies to develop and validate performance indicators related specifically to the outcomes of public access computing (PAC)

Through the use of a nationwide telephone survey, library case studies, and a nationwide Internet survey of public access computing patrons, this approach will generate generalizable quantitative data on the extent and distribution of the use of public access computing resources, as well as provide rich contextual data that will help in the understanding of how patrons use the computer and Internet connections in public libraries and the impact it has on their lives. Further, the mixed methods approach will allow for the examination of external factors that may influence patron outcomes, including the level library services and funding, community perceptions, and the availability of alternative modes of free access to computers and the Internet.
