Many business students rely heavily on the Web for research, in part because of their unfamiliarity with the breadth of their library's business resources (online and in print). This study sought to determine whether library instruction could impact undergraduate business students' atti tudes and use of three information formats: print materials, library data bases, and Web resources.

Results indicate that after library instruction, students held more favorable attitudes toward print resources and used them in their research more than they had initially expected. n today's fast-paced world, the students to the full array of research tools desire for expediency has at their disposal. Past research has dem prompted undergraduate stuonstrated that library instruction can in dents to place a premium on fluence students' general attitudes toward information that can be found quickly and easily. To this end, many students limit their research to electronic resources, choosing format over substance and con venience over accuracy. In particular, re liance on the World Wide Web as a pri mary-and often sole-research tool has impacted the quality and rigor of student projects and reduced students' familiar ity with more traditional print resources and bibliographic databases in their university's library collection. Given this trend, more than ever it is imperative that librarians, in collaboration with academic faculty, take a central role in introducing the library and its resources; more work must be done, however, to measure the impact of library instruction on students' perceptions of specific information for mats.
