    • • The major International information systems & services are INIS, AGRIS, INSPEC, BIOSIS, MEDLARS, etc. • MEDLARS (Medical Literature Analysis & Retrieval System) is an online computer searching system & a bibliographic service started by NLM, Maryland (USA).
    • National Library of Medicine (NLM): An Overview • The NLM, on the campus of the National Institutes of Health in Bethesda, Maryland (USA), founded in 1836. • In 1956, NLM came under the Act of Congress of USA & was declared an apex library in the field of Medical Sciences.
    • NLM… • The world’s largest biomedical library, NLM maintains & makes available a vast print collection & produces electronic information sources on a wide range of topics. • It also supports & conducts research development, & training in biomedical informatics & health information technology.
    • Publications of NLM • Index Medicus (1879)- Monthly • Medical Subject Headings (MeSH)-1983 • Cumulated Index Medicus (1992) • Abridged Index Medicus (1993)
    • MEDLARS • The work on MEDLARS began in 1960 & the system has several major revisions. • Came into operation in 1964.
    • MEDLARS System • MEDLARS is a computerized storage & retrieval system to furnish bibliographic access to NLM’s large biomedical collection. • It became operational with the 1st computerproduced issue of ‘Index Medicus’, a comprehensive subject- author index, to the articles from the world’s biomedical journals.
    • Activities of MEDLARS • Preparing of citations for the publication of Index medicus. • Maintenance of several computer- readable databases including MEDLINE. • Operation of online network. • Provides SDILINE.

    • Indexing • MEDLINE uses Medical Subject Headings (MeSH) for information retrieval. • Engines designed to search MEDLINE (such as PubMed & Entrez) generally use a Boolean expression combining MeSH terms, words in abstract and title of the article, author names, date of publication, etc.
    • Inclusion of journals • More than 6,000 of the world's leading biomedical journals are indexed in MEDLINE. • Selection is based on the recommendations of a panel, the Literature Selection Technical Review Committee (LSTRC), based on scientific policy and scientific quality.
    • • PubMed is a free database comprises more than 22 million citations for biomedical literature from MEDLINE, life science journals, & other online books. • Citations may include links to full- text content from PubMed Central & publisher websites. • Available via the NCBI Entrez retrieval system.
    • • MedlinePlus is a free web service produced & maintained by NLM. • Provides consumer health information for patients, families, & health care providers. • Brings together information from the US.
