• NLM’s premiere bibliographic database, indexing over 19 million references to journal articles, over sixty years
• Journals are selected for indexing by the Literature Selection Technical Review Committee (LSTRC), an NIH-centered advisory board.
• The committee ensures representation by women and minorities, members from different regions across the US
• PubMed’s primary component
