A microcomputer and hard disk were used to set up an automated card catalog in an Edmonton (Alberta) elementary school learning resource center to determine if a computerized card catalog would help elementary students to access learning resource materials, thereby enhancing their learning. Instead of using a traditional card catalog, students from grades 1 to 6 typed on the microcomputer the author, title, or subject desired. The computer replied with a list of available center materials as well as their locations. Evaluation included pre- and posttests on computer literacy with a sample of second and fifth grade students, interviews with the teacher/librarian and library aide, teacher and student questionnaires, and records of circulation data, librarian activities, how the librarian and aide spent their time before and after implementation of the project, and capital and maintenance costs. Results showed greater student interest and use of the library, a dramatic increase in the use of the automated card catalog over the traditional type, and more use of non-fiction materials by students in grades 1 to 3. Students were able to access material more easily, and the computerized catalog was less difficult for them to use than the traditional one. An appendix includes data gathering instruments.
