The UW-Madison Libraries Library Course Page system is used to deliver electronic reserves materials and course-focused library instruction webpages to students. As part of a rewrite of our system we broke the application into three component pieces: a file repository, a course timetable data service, and an interface application for building and viewing individual course pages. The new three-piece system was written with an inward facing service-oriented architecture that allowed us to choose the best technologies to solve each of the tasks the entire system needs to accomplish. - Tom Keays
