Thomas Pynchon in the context of "Systems novel"

The encyclopedic novel is a genre of complex literary fiction which incorporates elements across a wide range of scientific, academic, and literary subjects. The concept was coined by Edward Mendelson in criticism of Gravity's Rainbow by Thomas Pynchon, defined as an encyclopedia-like attempt to "render the full range of knowledge and beliefs of a national culture, while identifying the ideological perspectives from which that culture shapes and interprets its knowledge". In more general terms, the encyclopedic novel is a long, complex work of fiction that incorporates extensive information (which is sometimes fictional itself), often from specialized disciplines of science and the humanities. Mendelson's essays examine the encyclopedic tendency in the history of literature, considering the Divine Comedy, Don Quixote, Faust, and Moby-Dick, with an emphasis on the modern Ulysses and Gravity's Rainbow. Commonly cited examples of encyclopedic novels in the postmodern period include, in addition to Pynchon, Richard Powers' The Gold Bug Variations (1991), David Foster Wallace's Infinite Jest (1996), and Don DeLillo's Underworld (1997). Other literary critics have explored the concept since, attempting to understand the function and effect of "encyclopedic" narratives, and coining the related terms systems novel and maximalist novel.

Gravity's Rainbow is a 1973 novel by the American writer Thomas Pynchon. The narrative is set primarily in Europe at the end of World War II and centers on the design, production and dispatch of V-2 rockets by the German military. In particular, it features the quest undertaken by several characters to uncover the secret of a mysterious device, the Schwarzgerät ('black device'), which is slated to be installed in a rocket with the serial number "00000".

Traversing a wide range of knowledge, Gravity's Rainbow crosses boundaries between high and low culture, between literary propriety and profanity, and between science and speculative metaphysics. It shared the 1974 US National Book Award for Fiction with A Crown of Feathers and Other Stories by Isaac Bashevis Singer. Although selected by the Pulitzer Prize jury on fiction for the 1974 Pulitzer Prize for Fiction, the Pulitzer Advisory Board was offended by its content, some of which was described as "'unreadable', 'turgid', 'overwritten', and in parts 'obscene'". No Pulitzer Prize was awarded for fiction that year. The novel was nominated for the 1973 Nebula Award for Best Novel.

Postmodern literature is a form of literature that is characterized by the use of metafiction, unreliable narration, self-reflexivity, and intertextuality, and which often thematizes both historical and political issues. This style of experimental literature emerged strongly in the United States in the 1960s through the writings of authors such as Kurt Vonnegut, Thomas Pynchon, William Gaddis, Philip K. Dick, Kathy Acker, and John Barth. Postmodernists often challenge authorities, which has been seen as a symptom of the fact that this style of literature first emerged in the context of political tendencies in the 1960s. This inspiration is, among other things, seen through how postmodern literature is highly self-reflexive about the political issues it speaks to.

Precursors to postmodern literature include Miguel de Cervantes' Don Quixote (1605–1615), Laurence Sterne's Tristram Shandy (1760–1767), James Hogg's Private Memoires and Convessions of a Justified Sinner (1824), Thomas Carlyle's Sartor Resartus (1833–1834), and Jack Kerouac's On the Road (1957), but postmodern literature was particularly prominent in the 1960s and 1970s. In the 21st century, American literature still features a strong current of postmodern writing, like the postironic Dave Eggers' A Heartbreaking Work of Staggering Genius (2000), and Jennifer Egan's A Visit from the Goon Squad (2011). These works also further develop the postmodern form.

The Crying of Lot 49 is a novel by the American author Thomas Pynchon. It was published by J. B. Lippincott & Co. on April 27, 1966. The shortest of Pynchon's novels, the plot follows Oedipa Maas, a young Californian woman who begins to embrace a conspiracy theory as she possibly unearths a centuries-old feud between two mail distribution companies. One of these companies, Thurn and Taxis, actually existed; operating from 1806 to 1867, Thurn and Taxis was the first private firm to distribute postal mail. Like most of Pynchon's writing, The Crying of Lot 49 is often described as postmodernist literature. Time magazine included the book in its list of the 100 best English-language novels from 1923 to 2005.
