Abstract

To become lifelong learners, students must acquire information retrieval skills for future as well as current information needs. Describes how the library use instruction programme at Northwest Missouri State University incorporates a heuristic model in which students continually evaluate and refine their information seeking practices while progressing through all levels of courses in diverse disciplines. Collegial partnerships with departmental faculty and ongoing instructional assessment are essential to the success of the programme
