Many journals publish some or all of their articles online. To find journal articles or summaries of publications, you can use a searchable database. A searchable database is a collection of Web pages or articles that have been published or posted by an interested group. There are searchable databases on virtually every topic. Well known databases include the Smithsonian Institute's Art Collection, the National Institutes of Health (NIH) Medical Library, and Medline.
Some publishers have searchable databases as well.
PubMed is a searchable database of particular interest to bio-technologists, especially those who are working on topics of medical or pharmaceutical interest.
