PMC – Free Archive of Biomedical and Life Sciences Journal Literature
PubMed Central® (PMC) is a free archive of biomedical and life sciences journal literature at the U.S. National Institutes of Health’s National Library of Medicine (NIH/NLM). In keeping with NLM’s legislative mandate to collect and preserve the biomedical literature, PMC serves as a digital counterpart to NLM’s extensive print journal collection. Launched in February 2000, PMC was developed and is managed by NLM’s National Center for Biotechnology Information (NCBI). As an archive, PMC is designed to provide permanent access to all of its content, even as technology evolves and current digital literature formats potentially become obsolete. NLM believes that the best way to ensure the accessibility and viability of digital material over time is through consistent and active use of the archive. For this reason, free access to all of its journal literature is a core principle of PMC. Please note, however, that free access does not mean that there is no copyright protection. As described on our copyright page publishers and individual authors continue to hold copyright on the material in PMC and users must abide by the terms defined by the copyright holder. In addition to its role as an archive, the value of PMC lies in its capacity to store and cross-reference data from diverse sources using a common format within a single repository. With PMC, a user can quickly search the entire collection of full-text articles and locate all relevant material. PMC also allows for the integration of its literature with a variety of other information resources that can enhance the research and knowledge fields of scientists, clinicians and others. 2.8 million articles are archived in PMC. This will be added to Healthcare Resources Subject Tracer™.
