In a world awash in data, information systems help provide structure and access to information. Since libraries build, manage, and maintain information systems, librarians and LIS students are often propelled onto the front lines of interactions between library users and technology. But what do librarians need to know to best meet their patron's needs? What exactly are information systems and how do they work?

Information expert Ratzan uses plain language, humor, and everyday examples like baseball and arithmetic to make sense of "information systems" (computer hardware, software, databases, the Internet). He also explores their characteristics, uses, abuses, advantages, and shortcomings for your library. Fun exercises and appendices are provided to illustrate key points in the book and measure understanding.
You can be a technophobe and still learn about systems and subsystems to represent, organize, retrieve, network, secure, conceal, measure, and manage information. This expert sourcebook addresses both theoretical and practical issues, and is complete with exercises, examples, terms, and charts that help clarify concepts to make your information system a success.
