Avicenna - A relatively new site geared towards health professionals.
Requires registration but offers free MEDLINE, Outcomes Database, a proprietary
medical terminology search engine, a pharmaceuticals and medicines index,
medical database, medical links and more. Medscape

(backfiles to 1966), AIDSLINE, KeywordsDocument retrieval by mail or fax
for a price.Healthgate
- Another place to do free MEDLINE searches. Some features require registration.
Document retrieval by mail or fax for a price.NlightN
- This search engine covers a host of scientific and scholarly databases
as well as the popular press and the WWW. Among the databases are MEDLINE
and Index Medicus (Abridged) but unfortunately, not CINAHL. Requires registration.
WWW searches are free, information from proprietary databases aren't. Costs
range from a few cents for each abstract retrieved to substantial to order
the full text version of articles from some databases. Physics
Around the World: Search for Physics and Other Information - The name
says it all. If you're looking for physics information this is a good place
to start. AltaVista
- The size of its database, the speed of its search engine, and the ability
to more narrowly define searches by using Boolean operators, specifying
which parts of documents to search, nesting, searching by date, and user
defined results ranking criteria gives Alta-Vista the edge when it comes
to finding specific information on the Web or in USENET newsgroups. Alta
Vista: Advanced Query Alta
Vista Simple QueryLycos
- With a database almost as large as [and sometimes more up to date than]
Alta Vista's, Lycos remains an excellent search tool although it would
benefit from a more full-featured search engine.All-in-One
Internet Search - Not sure where to start looking? The All-in-One search
page has links to enough search engines to keep even the most dedicated
information hunters happy.Yahoo
- Although Yahoo is more accurately categorized as an index, the size of
its index combined with the power of its search engine merits its inclusion
here as well.Searching
