1.a. Advantages of Topic-Oriented Directories
There are two major advantages of
topic-oriented directories. First of all they rely on a logical organization of
information. Unlike encyclopedias and other reference books that organize information in
alphabetical order, topic directories are organized by subject and topic. Therefore the
information (rather than spelling) becomes the navigator. Another benefit of this
information-based organization is that cross-references tend to exist, linking different
paths of research together.
The second advantage lies in the final
page that that was generated by our search for Monarch Butterflies. That final list of web pages will be a short and
concentrated list of resources, concentrated in that they will all be about butterflies
and moths. If you have used a search engine before, you know that a search of butterflies
will produce a very large list of resources, only some of which are actually about
butterflies. For instance a search of HotBot generates a list of 60,059 pages. Within the
first ten is a site advertising live butterflies for release at weddings. By contrast,
Yahoo produced a list of only 30 sites, each one about butterflies.
