Abstract
The development of education libraries cannot be understood outside the context of education history. Changes in educational practices and technology spurred three phases of development in the history of education libraries. Early examples, often called curriculum laboratories, developed as spaces to create educational materials where limited numbers existed. As standardized curriculum grew, common laboratories gave way to curriculum materials centers, which housed materials so that future teachers could preview them. The rise of audio-visual equipment transformed education libraries once again into centers housing a variety of instructional materials. This paper traces the development of education libraries through these three phases.
