Everything else is easy. ---rick Some of the information already exists in electronic form; Inertia, Policy, Money, Politics are the real obstacles. The Health Science Library (HSL) at UMAB provides a mini Med-Line service called MaryMed. At present the MaryMED data base is updated at most once or twice a month from magnetic tapes obtained from NLM. The following is a summary: } The MaryMED database contains citations to English language } articles in journals owned by the [HSL] Library. } } Contents of the MaryMED database: [Wed Dec 20 15:32:53 EST 1989] } JAN-DEC 1989 Updates 228,699 citations } JAN-DEC 1988 Updates 205,489 citations } NOV-DEC 1987 Updates 33,164 citations } ------- } 467,352 citations MaryMED averages roughly 600 citations a day while usenet generates about 2000 messages. The average MaryMED citation is about 1,500 bytes; the average usenet message is 2,358 bytes long. Usenet moves over 4 megabytes per day while MaryMED processes less than 1 megabyte per day. The usenet distributes messages among various branches and twigs of its newsgroups tree structure. The NLM likewise allows searches based on a tree structure of Medical Subject Headings. The USENET allows cross posting of a news article. MaryMED articles have many keywords associated with the reference that would be amenable for cross posting. MaryMed citations are limited to the HSL journals published in English and abstracted during the past two years. I would prefer a more complete search. The restriction to the current two years is both too long and too short. It is too short when initiating a search on a new subject where it is desired to locate reference 10, 20 or more years old. It is too short for the user wanting to search only the most recent month or two. MaryMed is a giant step forward for the HSL but only a small step toward an electronic research library. ---------------------------------------------------------------------- Albert Hybl, PhD.
