The Bell Jar is the only novel written by the American writer and poet Sylvia Plath.
 Originally published under the pseudonym "Victoria Lucas" in 1963, the novel is semi-autobiographical, with the names of places and people changed.
 The book is often regarded as a "roman à clef" since the protagonist's descent into mental illness parallels Plath's own experiences with what may have been clinical depression.
 Plath died by suicide a month after its first UK publication.
 The novel was published under Plath's name for the first time in 1967 and was not published in the United States until 1971, in accordance with the wishes of both Plath's husband, Ted Hughes, and her mother.
 The novel has been translated into nearly a dozen languages.
 The novel, though dark, is often read in high school English classes.
The Sylvia Plath effect is the phenomenon that poets are more susceptible to mental illness than other creative writers.
 The term was coined in 2001 by psychologist James C. Kaufman.
 Although many studies (e.g., Andreasen, 1987; Jamison, 1989; Ludwig, 1995) have demonstrated that creative writers are prone to experience mental illness, this relationship has not been examined in depth.
 This early finding has been dubbed "the Sylvia Plath effect", and implications and possibilities for future research are discussed.
 Kaufman's work further demonstrated that female poets were more likely to experience mental illness than any other class of writers.
 In addition, female poets were more likely to be mentally ill than other eminent women, such as politicians, actresses, and artists.

Cuban literature is the literature written in Cuba or outside the island by Cubans in Spanish language.
 It began to find its voice in the early 19th century.
 The major works published in Cuba during that time were of an abolitionist character.
 Notable writers of this genre include Gertrudis Gomez de Avellaneda and Cirilo Villaverde.
 Following the abolition of slavery in 1886, the focus of Cuban literature shifted.
 Dominant themes of independence and freedom were exemplified by José Martí, who led the modernista movement in Latin American literature.
 Writers such as the poet Nicolás Guillén focused on literature as social protest.
 Others, including Dulce María Loynaz, José Lezama Lima and Alejo Carpentier, dealt with more personal or universal issues.
 And a few more, such as Reinaldo Arenas and Guillermo Cabrera Infante, earned international recognition in the postrevolutionary era.
