Title: Literary hostility to J. R. R. Tolkien
Content:  J. R. R. Tolkien (1892–1973) was an English Roman Catholic writer, poet, philologist, and academic, best known as the author of the high fantasy works The Hobbit and The Lord of the Rings. In 1954–55, The Lord of the Rings was published. In 1957, it was awarded the International Fantasy Award. The publication of the Ace Books and Ballantine paperbacks in the United States helped it to become immensely popular with a new generation in the 1960s. The book has remained so ever since, ranking as one of the most popular works of fiction of the twentieth century, judged by both sales and reader surveys. In the 2003 "Big Read" survey conducted by the BBC, The Lord of the Rings was found to be the "Nation's best-loved book." In similar 2004 polls both Germany and Australia also found The Lord of the Rings to be their favourite book. In a 1999 poll of Amazon.com customers, The Lord of the Rings was judged to be their favourite "book of the millennium." The popularity of The Lord of the Rings increased further when Peter Jackson's film trilogy came out in 2001–2003.
Title: J. R. R. Tolkien
Content:  In 1980, Christopher Tolkien published a collection of more fragmentary material, under the title Unfinished Tales of Númenor and Middle-earth. In subsequent years (1983–1996), he published a large amount of the remaining unpublished materials, together with notes and extensive commentary, in a series of twelve volumes called The History of Middle-earth. They contain unfinished, abandoned, alternative, and outright contradictory accounts, since they were always a work in progress for Tolkien and he only rarely settled on a definitive version for any of the stories. There is not complete consistency between The Lord of the Rings and The Hobbit, the two most closely related works, because Tolkien never fully integrated all their traditions into each other. He commented in 1965, while editing The Hobbit for a third edition, that he would have preferred to rewrite the book completely because of the style of its prose.
