Computer Science Computer Science Education Graduate Study Information Science Library Education Library Schools Library Science Professional Education Program Descriptions A brief analysis of educational activities in the field of information science is followed by summary descriptions of degree programs in the field available in twenty universities and institutions in the United States. When possible, descriptions were taken directly from the material sent by directors of the various programs. Included are (1) all programs with information science as the main area of concentration, (2) programs in library science with an available major in information science, and (3) programs in computer science only when the option to specialize in the area of information science is available.
