As you might expect, you may try different search engines thinking you re expanding your view of the Web without finding any additional content. That s because many of the major search services share data. For example, Excite, AOL Netfind, and Netscape Search use essentially the same database and search engine. The MS Search uses Inktomi for content and brains. All the more reason to use a meta search or a directory instead of an ordinary search engine.
Directories list and organize Web sites by category.
They are most useful for identifying services and resources in an uncluttered fashion. Think of them as an analog to the Yellow Pages only they aren't limited to businesses. Directories list only the entry page to site. This means that if the information you really need is on a page other than the main page, you may never find it. You should understand that directories can have search engine features as well.
