Extremely Loud & Incredibly Close is best read alongside other modern and contemporary works of realist fiction that have a strong, quirky, compelling protagonist—especially novels written from the perspective of a precocious kid. These novels usually follow the narrator on some sort of quest, through which the protagonist himself also grows up. The most iconic twentieth example of a novel in this type of voice is J.D. Salinger’s
The Catcher in the Rye (1951), also a deeply symbolic novel about a boy traveling around New York City and mourning a family member’s death. Mark Haddon’s
The Curious Incident of the Dog in the Nighttime (2003) is written from the point of view of a boy with Asperger’s disease, a form of high-functioning autism in which people are often extremely precocious but find difficulty navigating their way around day-to-day interactions without elaborate rituals and patterns. Many reviewers of
Extremely Loud & Incredibly Close diagnose Oskar with Asperger’s disease because of his verbal precocity and strange personal quirks. Junot Diaz’s
The Brief Wondrous Life of Oscar Wao, set near New York, also has a protagonist named Oscar/Oskar; more importantly, Diaz’s novel, like Foer’s, uses a parallel narrative between the protagonist in the present and his family’s history.
Extremely Loud & Incredibly Close can also be read alongside imaginative retellings of World War II stories, especially books such as Kurt Vonnegut’s
Slaughterhouse-Five (1969) that weave together plots from different time periods. Although Junot Diaz and Kurt Vonnegut include fantasy in their fictional worlds, whereas Jonathan Safran Foer’s novel is more realistic, Foer uses many recurring symbols and carefully plotted elements that draw from the structures of legend and superstition.
