Routledge (//) is a British multinational publisher. It was founded in 1836 by George Routledge, and specialises in providing academic books, journals, & online resources in the fields of humanities and the sciences. The company publishes 1,800 journals & 2,000 new books each year and their backlist encompasses over 35,000 titles.
In 1998 Routledge became a subdivision and imprint of its former rival, Taylor & Francis Group 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.
The firm originated in 1836, when Camden bookseller George Routledge published an unsuccessful guidebook, The Beauties of Gilsand with his brother-in-law W H (William Henry) Warne as assistant. In 1848 the pair entered 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 which was mainly due to the mass hysteria in the 1840s due to Railway Mania 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 though selling pirated reprints of Uncle Tom's Cabin, which allowed for it to be able 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. 
The company was restyled as 1858 as Routledge, Warne & Routledge when George Routledge's son, Robert Warne Routledge, entered the partnership. Frederick Warne eventually left the company after the death of his brother W H Warne in May 1859 (died aged 37). Gaining rights to some titles, he founded Frederick Warne & Co in 1865, which became known for its Beatrix Potter books.
However, by 1902, the company was running close to bankruptcy, but, following a successful restructuring, was able to recover and began to acquire and merge with other publishing companies. These early 20th-century acquisitions and mergers brought with them lists of notable scholarly titles, and it is from 1912 onwards that Routledge & Kegan Paul, as the company name, became increasingly concentrated on and involved with the academic and scholarly publishing business. It was soon particularly known for its titles in the social sciences.
In 1985, Routledge & Kegan Paul joined with Associated Book Publishers (ABP), which was later acquired by International Thomson in 1987. Under Thomson's ownership, Routledge's name and operations were retained, and, in 1996, a management buyout financed by the European private equity firm Cinven saw Routledge operating as an independent company once again. Just two year later, Cinven and Routledge's directors accepted a deal for Routledge's acquisition by Taylor & Francis Group (T&F), with the Routledge name being retained as an imprint and subdivision. In 2004, T&F became a division within Informa plc after a merger. Routledge continues as a publishing arm and imprint under the T&F division, with a majority of its titles' issued as academic humanities and social sciences books.
Routledge has published many of the greatest thinkers and scholars of the last hundred years, including Adorno, Einstein, Russell, Popper, Wittgenstein, Jung, Bohm, Hayek, McLuhan, Marcuse and Sartre.
