PubMed Central is a free digital archive of full articles, accessible to anyone from anywhere via a web browser (with varying provisions for reuse). Conversely, although PubMed is a searchable database of biomedical citations and abstracts, the full-text article resides elsewhere (in print or online, free or behind a subscriber paywall).
PubMed is a openly-accessible free database which includes primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. The United States National Library of Medicine (NLM) at the National Institutes of Health maintains the database as part of the Entrez system of information retrieval.
Open access articles can be found with a web search, using any general search engine or those specialized for the scholarly and scientific literature, such as Google Scholar, OAIster, base-search.net, [266] and CORE [267] Many open-access repositories offer a programmable interface to query their content.
Counterintuitively, a search that returns thousands of articles is not guaranteed to be comprehensive. Unlike using a typical Internet search engine, PubMed searching MEDLINE requires a little investment of time. Using the MeSH database to define the subject of interest is one of the most useful ways to improve the quality of a search.
Open Journal Systems (OJS) was conceived to facilitate the development of open access, peer-reviewed publishing, providing the technical infrastructure for the presentation of journal articles along with an editorial-management workflow, including article submission, peer-review, and indexing. OJS relies upon individuals fulfilling different ...
It is a common misconception that because a source appears in PubMed it is published by, or has the approval of, the National Institutes of Health (NIH), National Center for Biotechnology Information (NCBI), or the US government. These organisations support the search engine but lend no particular weight to the content it indexes.
The strategies in this field have been applied to the biomedical literature available through services such as PubMed. In recent years, the scientific literature has shifted to electronic publishing but the volume of information available can be overwhelming. This revolution of publishing has caused a high demand for text mining techniques.
