With a heritage stretching back nearly 200 years, HarperCollins is one of the world's foremost English-language publishers, offering the best quality content right across the spectrum, from cutting-edge contemporary fiction to digital hymnbooks and pretty much everything in between. In the UK, the Glasgow-based William Collins & Sons was founded in 1819 and published a range of bibles, atlases and dictionaries, later including classic authors HG Wells, Agatha Christie, JRR Tolkien and CS Lewis. The original Harper Brothers Company was established in New York City in 1817 and over the years published the works of Mark Twain, the Bronte Sisters, Thackeray, Dickens, John F Kennedy and Martin Luther King Jr. In 1987, Harper & Row, as it had then become, was acquired by News Corporation. The worldwide group was formed following News Corp's 1990 acquisition of William Collins & Sons. Today we publish some of the world's foremost authors, from Nobel prize-winners to worldwide bestsellers recent successes including the Booker-winning Wolf Hall and Bring Up The Bodies by Hilary Mantel, and George RR Martin's blockbusting A Song of Ice and Fire series.
