Creating Cool Web Sites with HTML, XHTML, and CSS

What makes this electronic travel from Web site to Web site so compelling for me (and for
millions of other users) is that there aren’t just thousands or tens of thousands of Web documents
to visit—there are millions. So many pages exist, in fact, that no one has ever visited
all of them. Because so many documents are available, finding the information you’re seeking
is perhaps the single greatest challenge on the Internet.
