At the end of 2007, SirsiDynix introduced the first version of Symphony, its new flagship Integrated Library System (ILS). This article begins with a look at the evolution of Symphony, user reactions to Symphony, and Symphony's design and functionality. The authors, along with a team of librarians from various functional areas, have completed testing of four Symphony 3.2.1 core modules and iBistro, the online catalog, at the King Fahd University of Petroleum & Minerals (KFUPM) Library in Dhahran, Saudi Arabia. The results and observations from this testing provides an overview of Symphony's strengths as well as its complexities and constraints. The authors present a list of the positive attributes they identified as they studied SirsiDynix's new flagship ILS, Symphony. (Contains 2 figures.)
