Educational dissemination has contributed a number of innovative concepts and strategies to information science. Much-misunderstood ERIC, which combines research reports with policy documents and teaching materials, is one of the first and best examples of a field-oriented rather than discipline-oriented database. Building on ERIC, federal education agencies have experimented continuously with extension or outreach to the school districts. Three extension roles have emerged among agents or specialists who work with the schools; the concept of entitlement helps to explain differences among the roles. Education's strong equity premises have led to the concept of information equity as a prerequisite of equal access and equal treatment. To serve millions of educators in more than 15,000 school districts and 3,000 colleges and universities, innovative dissemination in education should now focus on the concepts of efficiency and economies of scale.
