A great deal of what is on the Internet is going to remain inaccessible to search
engines, either because the information is password-protected, is behind a firewall,
requires registration and/or payment to view, etc. In short, this information either is
not intended for public viewing or there is a price to do so. There is, however, a
substantial amount of data that is meant for public consumption but is not indexed by
search engine spiders: public databases. These run the gamut from very technical
medical or scientific databases (e.g., MEDLlNE, NASA EOSDIS) to frivolous (e.g.,
Jokes.corn). How do you find these online databases and other "hidden" websites?
BUBL
http://www.bubl.ac.uk/
There are a number of very good websites devoted entirely or mostly to tracking
down web databases and other "hidden" resources. One of the most impressive
catalogs of hard to find sites is BUBL. First established in 1990, the name stood for
BUlletin Board for Libraries. Today, BUBL offers a huge index of resources primarily
for academic researchers. BUBL's index can be sorted by topic, alphabetically, by
country, or by Dewey Decimal System. Deep Web Research
