There are also links to other subjects that are on the same level in the same branch of the hierarchy. Britannica has a helpful Expanded Outline page that shows every subject in the top two levels of the subject hierarchy. Reviews All listed sites are reviewed. Reviews vary in length from a line or two to over 100 words. Average length is probably about two to three sentences.
Reviews tend to be longer for higher rated sties.
For each site, there is also a Site Statistics page that tells who owns the site, how old it is, an estimate of how often it gets visited, a rating of how fast its connection is, and a list of related links. Ratings Most sites are rated from one to five stars. A one-star rating does not mean that the site is bad, just that it's not as good as some other sites in the directory. Different level ratings don't appear with equal frequency. You can include an AltaVista search at the same time if you so desire.
