Science.gov is a free, inte­grated single-search gate­way to reli­able sci­ence and tech­nol­ogy infor­ma­tion from 17 orga­ni­za­tions within 13 fed­eral sci­ence agen­cies. In this new 5.0 ver­sion,  launched on Sept. 15th, there are 7 addi­tional por­tals or data­bases that quadru­ple its content.  New con­tent includes patents, tox­i­col­ogy data, e-prints from the Dept. of Energy and OSTI, and jour­nal archives from PubMed Cen­tral, and Cancer.gov.

The search engine is improved with clus­ter­ing tech­nol­ogy, and Science.gov now pro­vides links to sci­ence news, the EurekAlert! and Wikipedia. 

“Science.gov is hosted by DOE’s Office of Sci­en­tific and Tech­ni­cal Infor­ma­tion (OSTI), within DOE’s Office of Sci­ence. In addi­tion to DOE, Science.gov is sup­ported by con­tribut­ing mem­bers of the Science.gov Alliance, includ­ing the Depart­ments of Agri­cul­ture, Com­merce, Defense, Edu­ca­tion, Health and Human Ser­vices, and the Inte­rior, the Envi­ron­men­tal Pro­tec­tion Agency, the Gov­ern­ment Print­ing Office, the Library of Con­gress, the National Aero­nau­tics and Space Admin­is­tra­tion and the National Sci­ence Foun­da­tion, with sup­port from the National Archives and Records Administration.”
