Overview
The term “invisible web” was used for the first time in 1994 by American specialist Jill Ellsworth. She coined this expression for the kind of information that was not accessible by using the search engines of the time. Nowadays the Internet is divided into two parts – on the one hand the visible and surface web and on the other hand an up to 500 times larger and invisible, opaque or deep web. It is in this invisible web that a large quantity of valid medical data is to be found. This paper contains some links to several sources.
Key words:
invisible web, medical information, searching.
