In that case, a Web index is a better bet.
Web indexes are online catalogues that organize Web pages into categories.
Each category is then broken down into subcategories that focus on one topic or subject area. After you find a subcategory that interests you, you can browse through its pages for the information you need. Each index categorizes things differently, and each has its strong and weak points, so you may have to try several before you can find the kind of information you need. Each guide creates an information center about his or her passion, be it fishing, math, Silicon Valley life, trivia, or history. Each guide site includes feature stories about the topic, a newsletter, chats, and well-organized links to related sites.
