I believe that invisible web (databases) has it's own advantages and disadvantages as compared to search engines, meta-search engines or subject directories. Databases allows get information mainly on newspaper articles or journals from credible sources such as world newspapers or famous schools in the world.
We have TP databases such as Lexis Nexis to use. Should the need arise, I will use databases while doing projects or research in my diploma. Currently, I'm a student of Mechantronic Enginneering.. There are subjects need us to do newspaper article analysis. It is to look through hardcopy newspaper to find a relevant topic to analyze on.
But by using a database such as Lexis Nexis, I can simply key in the dates to search between and the keywords relating to the topic I am researching on.
