Funding Support - 2007
An important aspect of scientific publication is the indication of funding support. The Medical Subject Headings (MeSH®), which is used by the National Library of Medicine® (NLM®) to describe the contents of journal articles for MEDLINE®, includes publication types to cover financial support of the research that resulted in the published paper when that support is mentioned in the article:
- Research Support, U.S. Gov't, P.H.S.
- Research Support, N.I.H., Extramural
- Research Support, N.I.H., Intramural
- Research Support, U.S. Gov’t, Non-P.H.S.
- Research Support, Non-U.S. Gov’t
These publication types are searchable in PubMed®. The table below gives the number of PubMed citations retrieved as of February 5, 2007. Research Support, U.S. Gov't, P.H.S.; Research Support, U.S. Gov't, Non-P.H.S.; and Research Support, Non-U.S. Gov't have been used since 1975. Research Support, N.I.H., Extramural and Research Support, N.I.H., Intramural have been used since June 2005. It is important to remember that these publication types may be present on any citation regardless of its publication date as long as it was completely processed during or after 1975 and 2005, respectively.
