In fact one of the biggest complaints we hear concerns the difficulty of targeting information. Searching the Net requires part skill, part luck and a little bit of art. Fortunately, a number of free online resources can help with the hunt. There are literally dozens of these tools to help you locate what you're looking for. The trick though, is understanding how they work, so you can use the right tool for the job.
Directories are good at identifying general information.
They group websites together under similar categories, such as Internet tutorials, English universities and Paris museums. The results of your search will be a list of websites that cover the subject you are searching for. If you're interested in the Louvre museum, for instance, try using a directory. But let's say you want more specific information, such as biographical information about Leonardo da Vinci. Web indexes are the way to go, because they search all the contents of a site, not just the file name.
