3.3.9.3 Search engines
A huge number of search engines help students to find additional information. Nevertheless, the great number of search engines to chose from make life quite hard for students. They can use ``meta'' search engines which give them the result of several search engines combined, but often users get too much information and good skills are needed to pick the right document which hopefully contains useful information. The fact that everybody can publish on the WWW does not help either.
An international independent rating system is needed. Well known publishing
companies could, for instance, label documents according to reliability, and
provide the right keywords for search engines. The
PICS
project of the World Wide Web Consortium
is an example for such a labelling system.
