Data on the characteristics, information needs, and information dissemination patterns of actual and potential users of educational information were gathered through field interviews with persons representing a variety of educational roles and geographical locations (Vol. I) as well as through a nationwide mail questionnaire survey (Vol. II). Questions for the study were generated from an Educational Information Use Model which hypothesized relationships between user characteristics, information needs, and information sources employed. Results indicate that while there are many differences among respondents for the variables analyzed, there are distinct patterns of information use related to personal style and type of educational position held. This study forms half of a larger study intended to provide guidance for decision making and planning at all levels in the United States Education Information Service complex. Appended are the mail survey sampling design and the mail survey instrument. (STS)
