How is MEDLINE produced?
MEDLINE is the product of many information specialists at the National Library of Medicine: serials librarians who obtain journal subscriptions and check in the individual journal issues; indexers–biomedical subject specialists–who analyze the subject content of articles and describe concepts that are discussed, using the Medical Subject Headings (MeSH®) controlled vocabulary; and computer and information specialists who develop and maintain the retrieval system. Every journal issue and article cited in MEDLINE has been reviewed and inspected by many individuals.
