Not all original reviews, however, were so kind. New York Times reviewer Judith Shulevitz criticized the "pedantry" of Tolkien's literary style, saying that he "formulated a high-minded belief in the importance of his mission as a literary preservationist, which turns out to be death to literature itself. Critic Richard Jenkyns, writing in The New Republic, criticized a perceived lack of psychological depth. Both the characters and the work itself are, according to Jenkyns, "anemic, and lacking in fiber. Even within Tolkien's literary group, The Inklings, reviews were mixed. Hugo Dyson complained loudly at its readings, and Christopher Tolkien records Dyson as "lying on the couch, and lolling and shouting and saying, 'Oh God, no more Elves.' However, another Inkling, C. S. Lewis, had very different feelings, writing, "here are beauties which pierce like swords or burn like cold iron. Here is a book which will break your heart." Despite these reviews and its lack of paperback printing until the 1960s, The Lord of the Rings initially sold well in hardback.
Several other authors in the genre, however, seemed to agree more with Dyson than Lewis. Science-fiction author David Brin criticized the book for what he perceived to be its unquestioning devotion to a traditional elitist social structure, its positive depiction of the slaughter of the opposing forces, and its romantic backward-looking worldview. Michael Moorcock, another famous science fiction and fantasy author, is also critical of The Lord of the Rings. In his essay, "Epic Pooh", he equates Tolkien's work to Winnie-the-Pooh and criticizes it and similar works for their perceived Merry England point of view. Incidentally, Moorcock met both Tolkien and Lewis in his teens and claims to have liked them personally, even though he does not admire them on artistic grounds.
In 1957, it was awarded the International Fantasy Award. Despite its numerous detractors, the publication of the Ace Books and Ballantine paperbacks helped The Lord of the Rings become immensely popular 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 works of Tolkien have generated a body of academic research, studying different facets such as
A first avenue towards literary respectability of Tolkien's works was opened by Tom Shippey's 1982 The Road to Middle-earth. The pace of scholarly publications on Tolkien has increased dramatically in the early 2000s. The dedicated journal Tolkien Studies has been appearing since 2004.
Lobdell (2006) evaluating the reception of Tolkien in mainstream literary establishment (as opposed to dedicated Tolkien scholarship) cites the widely quoted negative critique Edmund Wilson and the partly favourable one by Edwin Muir and conclues that
Richard C. West compiled an Annotated Checklist of Tolkien Criticism (2nd ed., Kent State University Press, 1981)
Marxist critics vilified Tolkien for his social conservativism, and for the "veiled geopolitics" implied in readings that interpret Sauron's Mordor and Sharkey's dictatorship in the Shire are parodies of Soviet Communism (Oberhelman 2006). E.P. Thompson in 1981 blames the cold warrior mentality on "too much early reading of The Lord of the Rings". Inglis (1983) modifies earlier accusation of fascism against Tolkien, but still maintains that the novel is an "political fantasy" for escapist middle-class readers in modern capitalist society. Griffin (1985) examines Tolkien in relation to Italian neofascism, again suggesting a proximity of Tolkien's ideals to those of the radical right. Ironically, these interpretations run directly counter to the adoption of The Lord of the Rings into alternative "hippie" counter-culture and the environmental movement.
Tolkien was an accomplished philologist of Anglo-Saxon, but has left a comparatively meagre output of academic publications. His works on Anglo-Saxon philology which have received the most recognition is Beowulf: The Monsters and the Critics, a 1936 lecture on the interpretation of the Beowulf epic, and his identification of what he termed the "AB language", an early Middle English literary register of the West Midlands. Outside Anglo-Saxon philology, his 1939 lecture On Fairy Stories is of some importance to the literary genres of fantasy or mythopoeia. His 1930 lecture A Secret Vice addressed artistic languages at a time when the topic was of very limited visibility compared to the utilitarian projects of auxiliary languages. His 1955 valedictory lecture English and Welsh expounds his philosophy of language, notably his notion of native language and his views on linguistic aesthetics (c.f. cellar door). Smith (2007) is a monograph on Tolkien's philosophy of language.
Tolkien's The Hobbit, a children's book, was first published in 1937, and it proved popular. However, The Lord of the Rings, first published in 1954 through 1955, would give rise to the fandom as a cultural phenomenon.
Bootleg paperbacks published by Ace Books eventually found their way into colleges in the U.S.A. in the 1960s. In response, a revised, authorised edition was published by Ballantine Books. The "hippie" following latched onto the book, giving its own spin to the work's interpretation, such as the Dark Lord Sauron representing the United States military draft during the Vietnam War, to the chagrin of the author who stated that "Many American fans enjoy the books in a way which I do not".
Many fantasy series written in the period were created by fans of The Lord of the Rings, such as the Shannara books by Terry Brooks.
Although there were active Tolkien enthusiasts within science fiction fandom from the mid-1950s, true organized Tolkien fandom only took off with the publication of the second hardcover edition and the paperbacks in the 1960s.
Articles on The Lord of the Rings appeared regularly in the 1960s fanzine Niekas, edited by Ed Meskys. The first organized Tolkien fan group was "The Fellowship of the Ring", founded by Ted Johnstone at Pittcon, the 1960 Worldcon.
The Tolkien Society (U.K.) was founded in the U.K. in 1969, and remains active as a registered charity. The society has two regular publications, a bi-monthly bulletin of news and information, Amon Hen, and an annual journal, Mallorn, featuring critical articles and essays on Tolkien's work. They host several annual events, including a conference held at Oxford, Oxonmoot.
The Mythopoeic Society held its first Mythcon conference in 1970, which featured readings, a costume competition, an art show, and other events typical of science fiction conventions of the day.
A number of dedicated Tolkien Societies provide platforms for a combination of fandom and academic literary study in various countries. The most notable societies in the Anglosphere are The Tolkien Society (UK) and the Mythopoeic Society (USA).
The Deutsche Tolkien Gesellschaft (DTG) is a German association dedicated to the study of the life and works of J. R. R. Tolkien. Founded in 1997, it is based in Cologne. The DTG has more than 500 members (as of 2005) and is organised in a widespread network of local chapters. It is the main driving force of Tolkien reception in the German speaking countries (c.f. Honegger (2006); a Swiss Tolkien Society was founded in 1986, but dissolved in 2006; an Austrian Tolkien Society was founded in 2002). The DTG organized a seminar on Tolkien studies in Cologne in 2004, in Jena in 2005 and in Mainz in 2006. The conference proceedings are published in their Hither Shore yearbook.
The Tolkien Society Forodrim was founded in Sweden in 1972 and is one of the oldest Tolkien fan organizations. Forodrim was founded in a public toilet during a science fiction convention (possibly SF-Kongressen 1973) as a name change of Sam J Lundwall's Hyboria. Co-founders were Jörgen Peterzén and Anders Palm. 
Forodrim has an especially active group interested in Tolkienian linguistics, Mellonath Daeron.
Forodrim is Sindarin for "People of the North". The society is based in Stockholm, but has spawned daughter-organizations in Gothenburg and Malmö.
Kontu is the Finnish translation of "The Shire".
Shiro No Norite ("The White Rider") is a Tokyo-based group of fans, established in 1981. But reception of Tolkien's work among the Japanese public remained rather limited until the appearance of Jackson's films, after which there was a surge of interest.
In 2001, shortly before the release of the movies, the first Greek on-line community was formed in a promotional web site
which in 2002 founded an official group of fans under the name The Prancing Pony. The group is unofficially divided in two 'smials', in Athens and Thessaloniki.
During and after the release of the movies, further Tolkien-related literature was published in Greek language (both original and translations) including biographies, reading companions etc.
