MEDICAL SEARCH ENGINES/WEBSITE LISTSMedical information on the Internet is growing and diversifying. Every month more information is added and it becomes more challenging to sift through the many sites to find the content you are looking for. Traditional search engines do not focus on medical sites, and therefore some very valuable sites are overlooked or not updated into the index. To date, there is no all-inclusive engine for searching medical sites. Nor is there a single engine that adequately and thoroughly indexes just the most reputable sites. These are a sampling of sites that will search for and retrieve up-to-date, applicable and current postings from peer-reviewed sources.
The NLM is a very large database and the efficiency of a search can be aided by a review of the MESH (medical subject heading) "trees" at http://www.nlm.nih.gov/mesh/ The mesh trees incorporate the specialized language of the NLM classification system. Failure to use the appropriate language will result in a null or irrelevant search. For example: the phrase kidney calculi should be used instead of kidney stones.
Medline the largest, most-used, best-known of NLM's databases; more than 9 million records (30,000+ added each month) more than 90% of all searching is done in Medline. Medline is an electronic index that provides citations/abstracts to one of the jewels of medical research, is an electronic index that provides citations/abstracts to some 3900 American and foreign biomedical journals since 1966. Medline is free, and is accessible from various sites, such as Medscape, Internet Grateful Med, and Healthgate.
Internet Grateful Med offers assisted searching of MEDLINE and ten other NLM databases. Each database must be searched separately. Click on the "Search Other Files" button to select from the ten other files. PREMEDLINE provides basic citations/abstracts before data is put into MEDLINE. It is updated each weekday with no subject headings or guarantee of quality control. Once a record is added to MEDLINE it is deleted from PREMEDLINE. OLDMEDLINE covers articles from 1964-1965, with citations only.
