- PubMed Central is a free digital database of full-text scientific literature in biomedical and life sciences. It grew from the online Entrez PubMed biomedical literature search system. PubMed Central was developed by the U.S. National Library of Medicine as an online archive of biomedical journal articles. The full text of all PubMed Central articles is available free. Some participating journals, however, delay release of their articles for a set time after paper publication (often six months). As of June 2007, the archive contains approximately 1,000,000 items, including articles, editorials, letters, and so on. It appears to be growing by at least 7% per year. As of September, 2004, PubMedCentral, PubMed, and related NLM service were handling approximately 1300 hits per second, and supplying 1.3 Terabytes of data per day.
