Where do students find out about courses they might take? Potentially, from just about anywhere: friends, bulletin boards, department Web sites, advisors, e-mails, or flyers posted in the halls. Of course, some of these sources are more trustworthy than others. Where should students go to get reliable information that can help them make wise decisions about which courses to take? This is the need that a course guide seeks to meet. The University of Minnesota, Twin Cities, and the University of Wisconsin-Madison have taken two different approaches to building online, centrally accessible course guides. Both institutions had common goals in building course guide systems: to create a single source of rich course information connected to the online class schedule and to minimize time and effort expended by faculty and staff on information dissemination and course registration. The universities' solutions demonstrate the range of possibilities available to institutions seeking to provide detailed course information to students. (Contains 1 figure.)
