Routledge (ˈraʊtlɪdʒ ) is a British multinational publisher. It was founded in 1836 by George Routledge, and specialises in providing academic books, journals and online resources in the fields of the humanities, behavioural science, education, law, and social science. The company publishes approximately 1,800 journals and 5,000 new books each year and their backlist encompasses over 140,000 titles. Routledge is claimed to be the largest global academic publisher within humanities and social sciences. In 1998, Routledge became a subdivision and imprint of its former rival, Taylor & Francis Group (T&F), as a result of a £90-million acquisition deal from Cinven, a venture capital group which had purchased it two years previously for £25 million. Following the merger of Informa and T&F in 2004, Routledge became a publishing unit and major imprint within the Informa "academic publishing" division. Routledge is headquartered in the main T&F office in Milton Park, Abingdon, Oxfordshire and also operates from T&F offices globally including in Philadelphia, Melbourne, New Delhi, Singapore, and Beijing. The firm originated in 1836, when the London bookseller George Routledge published an unsuccessful guidebook, The Beauties of Gilsland, with his brother-in-law W. H. (William Henry) Warne as assistant. In 1848, the pair entered the booming market for selling inexpensive imprints of works of fiction to rail travellers, in the style of the German Tauchnitz family, which became known as the "Railway Library". The venture was a success as railway usage grew, and it eventually led to Routledge, along with W H Warne's brother Frederick Warne, to found the company, George Routledge & Co. in 1851. The following year in 1852, the company gained lucrative business through selling reprints of Uncle Tom's Cabin, (in the public domain in the UK) which in turn enabled it to pay author Edward Bulwer-Lytton £20,000 for a 10-year lease allowing sole rights to print all 35 of his works including 19 of his novels to be sold cheaply as part of their "Railway Library" series.
