Understanding Information Systems: What They Do and why We Need Them

From Booklist
Unlike most books discussing information systems, this one is not oriented to a specific application, time, or technology. Instead, readers are treated to 16 chapters covering different aspects of information, among them description, representation, organization, retrieval, networking, security, concealment, measurement, and management of information. The computer, Internet, and music are also discussed in terms of information systems. Information is well articulated, insightful, and strengthened by illustrative exercises and helpful appendixes. The author's use of humor is a welcome addition, making the text more engaging and palatable. Although conceived for the general reader, this resource would most likely appeal to students and instructors in library and information studies or computer science. Mathphobic readers or those uncomfortable with quantitative data may find the text a bit daunting at times, but for those willing to make the effort, the rewards are great and plentiful. RBB
