Philosophical Transactions of the Royal Society
The Philosophical Transactions of the Royal Society (Phil. Trans.) is a scientific journal published by the Royal Society of London. It was established in 1665, making it the first journal in the world exclusively devoted to science, and it has remained in continuous publication ever since, making it the world's longest-running scientific journal. The slightly earlier Journal des sçavans can also lay claim to be the world's first science journal, although it contained a wide variety of non-scientific material as well. The use of the word "philosophical" in the title derives from the phrase "natural philosophy", which was the equivalent of what would now be generically called "science".
The first issue, dated 6 March 1665, was edited and published by the society's first secretary, Henry Oldenburg, some six years after the Royal Society had been founded. Oldenburg published the journal at his own personal expense and seems to have entered into an agreement with the Council of the Royal Society allowing him to keep any resulting profits. He was to be disappointed, however, since the journal performed poorly from a financial point of view during Oldenburg's lifetime. Over the centuries, many important scientific discoveries have been published in the Philosophical Transactions. Famous contributing authors include Isaac Newton, James Clerk Maxwell, Michael Faraday and Charles Darwin. In 1672, the journal published Newton's first paper New Theory about Light and Colours, which can be seen as the beginning of his public scientific career. The position of editor was sometimes held jointly and included William Musgrave (Nos 167 to 178) and Robert Plot (Nos 144 to 178).
In July 2011 programmer Greg Maxwell released through the The Pirate Bay, the nearly 19 thousand articles that had been published before 1923, and were therefore in the public domain. They had been digitized for the Royal Society by Jstor, for a cost of less than USD100,000, and public access to them was restricted through a paywall. In October of the same year, the Royal Society released for free all its articles prior to 1941, but denied that this decision had been influenced by Maxwell's actions. 
Current publication 
In 1887 the journal expanded and divided into two separate publications, one serving the Physical Sciences (Philosophical Transactions of the Royal Society A: Physical, Mathematical and Engineering Sciences) and the other focusing on the life sciences (Philosophical Transactions of the Royal Society B: Biological Sciences). Both journals now publish themed issues and issues resulting from papers presented at the Discussion Meetings of the Royal Society. Primary research articles are published in the sister journals Proceedings of the Royal Society, Biology Letters, Journal of the Royal Society Interface, and Interface Focus.
