PubMed is a free database accessing 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 information retrieval system. PubMed was first released in January 1996.

In addition to MEDLINE, PubMed provides access to:

Many PubMed records contain links to full text articles, some of which are freely available, often in PubMed Central and local mirrors such as UK PubMed Central.

Information about the journals indexed in PubMed is found in the NLM Catalog.

David John Haskins (born 24 April 1957, Northampton, England), better known as David J, is a British alternative rock musician. He was the bassist for the gothic rock band Bauhaus and Love and Rockets.

He is the older brother of Kevin Haskins, also a musician and member of Bauhaus.

David J wrote the lyrics of several Bauhaus songs (including their first single, "Bela Lugosi's Dead"). He sang backing vocals on many songs, and sang lead on "Who Killed Mr. Moonlight?". He began writing music for a solo career while still in the band, and continued after the band's breakup, releasing the dark Etiquette of Violence and Crocodile Tears and the Velvet Cosh, and played bass on two Jazz Butcher albums (A Scandal in Bohemia and Sex and Travel). J was also a part of the very short-lived band The Sinister Ducks, which included saxophonist Alex Green and comics writer Alan Moore. He also released a collaborative single, "Armour" / "Nothing" with artist and poet Rene Halkett, of the original Weimar Bauhaus school of art and design.
