A study of 522 university students was undertaken to determine how often they used their library and why, as well as to develop a general profile of college student library users. Descriptive statistics revealed that the majority of students used the library at least once a week. Obtaining a book or an article for a course paper was the most common reason cited for library use, followed by studying for a test, and then using the computerized indexes and online facilities. A setwise multiple regression analysis revealed that students who used the libraries most tended to be older, male, those who did not speak English as their native language, who lived the nearest to the academic library, who preferred to study alone, and who had the lowest levels of library anxiety. In addition, these students tended to visit the library either to study for a test, to read current newspapers, to read their own textbook, to use computerized indexes and online facilities, or to meet friends. The implications of these findings are discussed, as are recommendations for future research. (Contains 15 references.) (Author)
