E-DRUG: Free medline (4)
------------------------
Another FREE medline has since long been available at
http://www.healthgate.com/HealthGate/MEDLINE/search.shtml
A big problem with the MEDLINE access at this and other sites
is the limitations of the search engine. For example, at the
Healthgate site, a search on movement disorders associated
with SSRIs and sertraline in particular produced over 8000
references. A similar search at the NLM site produced 22.
The search engine at the NLM is much more sophisticated,
and provides the ability to follow threads attached to articles
of particular interest. The others do not.
The NLM site allows one to do an *effective* Boolean search.
The other sites do not. The search engine available there rivals
that of Ovid, which I consider the preeminent means of accessing
the NLM database.
Free does not equate with useful.
