Three web services offer e-mail alerts on subjects that you specify. Pubcrawler, at http://pubcrawler.gen.tcd.ie is a free “alerting” service that scans daily updates to the NCBI Medline (PubMed) and GenBank databases. PubCrawler can keep scientists informed of the current contents of Medline and GenBank, by listing new database entries that match their research interests.
The U.S. Food and Drug Administration’s Division of Drug Information maintains free e-mail alerting lists. If you are interested in adding your name to one of the lists, go to http://www.fda.gov/Drugs/ucm136245.htm.
For the latest consumer health information updates, you can subscribe to free e-mail announcements (in language you can understand) from Medline Plus, a service of the U.S. National Library of Medicine and the National Institutes of Health.
