A debut novel is the first novel a novelist publishes. Debut novels are often the author's first opportunity to make an impact on the publishing industry, and thus the success or failure of a debut novel can affect the ability of the author to publish in the future. First-time novelists (without a previous published reputation, such as in nonfiction, magazines, or journals), typically struggle to find a publisher. Sometimes new novelists will self-publish, because publishing houses will not risk the capital needed to market books by an unknown author to the public. Most publishers purchase rights to novels, especially debut novels, through literary agents, who screen client work before sending it to publishers. These hurdles to publishing reflect both publishers' limits in resources for reviewing and publishing unknown works, and that readers typically buy more books by established authors with a reputation than first-time writers.
Often an author's first novel will not be as complex stylistically or thematically as subsequent works and often will not feature the author's typical literary characteristics. Huffington Post's Dave Astor attributes these to two forces: first that authors are still learning their own unique style and audiences are more willing to read works from unknown authors if they resemble more conventional styles of literature. To prove his point, Astor provides examples of works, like J.R.R. Tolkien's The Hobbit (1937), Margaret Attwood's The Edible Woman (1969) and Charles Dickens' The Posthumous Papers of the Pickwick Club (1837), all of which don't have the complexity or stylistic characteristics for which audiences praise in the author's later work. Sometimes, instead of writing novels to begin their career, some authors will start with short stories, which can be easier to publish and allow authors to get started in writing fiction.
In contemporary British and American publishing markets, most authors receive only a small monetary advance before publication of their debut novel; in the rare exceptions when a large print run and high volume of sales are anticipated, the advance can be larger. For an example of an unusually high advance: in 2013, the highly anticipated City on Fire by Garth Risk Hallberg captured the attention of ten publishers who started a biding war that ended with Knopf buying the rights to the book for 2 million dollars. The book's film production rights were purchased soon after by producer Scott Rudin. 
There are numerous literary prizes for debut novels often associated with genre or nationality. These prizes are in recognition of the difficulties faced by debut novelists and bring attention to deserving works and authors. Some of the more prestigious awards around the world include the American Hemingway Foundation/PEN Award, the French Prix Goncourt du Premier Roman, the British Guardian First Book Award, the German Aspekte-Literaturpreis and the Japanese Noma Literary Prize.
According to the Oxford English Dictionary, the earliest attested usage of "first novel" is from 1876. However, the term is much older, with instances going back to at least 1800. The Oxford English Dictionary doesn't have an entry for "debut novel." The earliest usage of "debut novel" in the Google Books database is 1930 (as of 2011[update]). The Google Books Ngram Viewer shows it becoming more widely used after about 1980, gaining in popularity since.
