This book is an in-depth analysis of the factors that make a Website believable. The authors, two librarians, examine numerous aspects of Websites and point out how they can be used to evaluate sites as trustworthy sources of information or goods. They begin with 5 traditional evaluation criteria: authority, accuracy, objectivity, currency, and intended audience, and give examples of how these criteria apply to Websites. They also extend these criteria with evaluation measures that are specific to the medium. They then apply the evaluation criteria to different types of Websites: advocacy, business, informational, news, personal, and entertainment pages. This book is a must-have for libraries and researchers. It would also be very useful for serious Web designers who want to understand what kinds of design factors will bring credibility and respect to their Websites.
