LAB SESSION 5

The object of this lab is to explore the invisible Web (also called the hidden Web), as a rich information source particularly of the type mostly not found by searching of search engines. Furthermore, the object is also to explore sources that will help you in keeping up with the Web.

Some of the invisible Web sources are mentioned in the article (at RUL):
Price, G. (2001) Web Search Engine FAQs: Questions, Answers, and Issues. Searcher, 9 (9), 38-52.
