Get the results you want when you search the Internet. Picture a vast, echoing library, with row upon row of books, containing all the world's knowledge.
Citizens wander in from time to time and add a book wherever they please.
There are, however, a number of independent librarians who scurry about perusing and indexing the books. Each librarian's index is fiercely separate from the rest, and each index references only a fraction of the library's contents. No, it's a description of the Internet as we know it today. Even the best search engines index no more than one page in six. To extract useful information from the Internet's near-limitless resources, you must learn how and where to search.
