Websites of note

Donald Lindberg has been director of the US National Library of Medicine (NLM) since 1984 and has a large staff at Bethesda, Maryland who have assembled the world’s largest biomedical library. Lindberg welcomes us to delve into every significant program of the Library, from medical history to biotechnology. There is a feeling of purpose here and a welcome freedom from gratuitous advertisements and mood images. This is the home of MEDLINE, not just a link. The site is very simply laid out with obvious menu choices that lead to other lists of choices. The first choice is “Health Information” leading to MEDLINE/PubMed, MEDLINEplus, and the NLM Gateway. MEDLINE is NLM’s database of indexed journal citations and abstracts covering 4,500 journals with new citations added weekly. MEDLINE includes articles indexed from 1966 to the present. Citations prior to 1966 are located in OLDMEDLINE. A superset of library services is available through the PubMed portal of the NLM. PubMed includes many peripheral areas of chemistry and physics that are not included within the biological science limits of MEDLINE. If you choose MEDLINEplus, then the look and feel changes to a graphic, more contemporary style than the home page. There are lots of seductive browsing categories and latest news items, some of which distracted me away from the diminutive SEARCH box at the top left hand side that leads to the journal citations. Depending on how specific the search topic is, there may be hundreds of citations returned. The NLM have ingeniously arranged their report of “hits” to be categorized by further subcategories. For example, a crude search for “diabetes” returned the subcategories “Diabetes” (general articles), “Diabetic Eye Problems,” “Diabetic Foot,” “Diabetic Nerve Problems,” and “Juvenile Diabetes.” Making further choices leads to ever more specific areas, and of course the journal citations. For browsing, users can choose “Health Topics” (over 600 topics on conditions, diseases, and wellness), “Drug Information” (prescription and over-the-counter medicines), “Medical Encyclopedia” (with pictures and diagrams), “Dictionary” (spellings and definitions of medical words), and “Health News” from the past 30 days. Additional links are provided to US hospitals, local libraries, health organizations, and international sites. Within “Health Topics,” the subchoices are mostly derivatives of anatomy and pathology, but you can also choose the single topic “Food, Nutrition, and Metabolism.” The level of information here under “Health Topics” is inadequate for most university teaching, although the articles have simple diagrams that may be of use in teaching.
