Document 2: New Haven, Connecticut: Grove Street Cemetery, a National Historic Landmark which lies adjacent to Yale's campus, contains the graves of Roger Sherman, Eli Whitney, Noah Webster, Josiah Willard Gibbs, Charles Goodyear and Walter Camp, among other notable burials. The cemetery is known for its grand Egyptian Revival gateway. The Union League Club of New Haven building, located on Chapel Street, is notable for not only being a historic Beaux-Arts building, but also is built on the site where Roger Sherman's home once stood; George Washington is known to have stayed at the Sherman residence while President in 1789 (one of three times Washington visited New Haven throughout his lifetime).
Document 3: Oliver Twist: The novel was originally published in monthly instalments in the magazine Bentley's Miscellany, from February 1837 to April 1839. It was originally intended to form part of Dickens's serial, The Mudfog Papers. George Cruikshank provided one steel etching per month to illustrate each instalment. The novel first appeared in book form six months before the initial serialisation was completed, in three volumes published by Richard Bentley, the owner of Bentley's Miscellany, under the author's pseudonym, "Boz". It included 24 steel-engraved plates by Cruikshank.
Document 4: Durfee Hall: Durfee Hall was completed in 1871 under the direction of Russell Sturgis, Jr. (M.A., Honorary, Yale University, 1872) and received its name from the generous Yale benefactor Bradford M. C. Durfee, Esq., of Fall River, Massachusetts. It was the second of a set of three buildings Sturgis designed that include Farnam Hall and Battell Chapel, and was originally described simply as "large and costly." However, it was quickly recognized as the defining piece of architecture on Yale's campus, and by the late 19th century, it was referred to by "The New York Times" as "the centre of wealth at Yale" and as "one of the finest college dormitories in the United States."
Document 5: David Copperfield: David Copperfield is the eighth novel by Charles Dickens. The novel's full title is The Personal History, Adventures, Experience and Observation of David Copperfield the Younger of Blunderstone Rookery (Which He Never Meant to Publish on Any Account). It was first published as a serial in 1849 -- 50, and as a book in 1850. Many elements of the novel follow events in Dickens's own life, and it is often considered his veiled autobiography. It was Dickens' favourite among his own novels. In the preface to the 1867 edition, Dickens wrote, ``like many fond parents, I have in my heart of hearts a favourite child. And his name is David Copperfield. ''The novel describes the journey of the protagonist David Copperfield; modeled after Dickens himself, from impoverished and miserable childhood to becoming a successful and famous author. Like some of his other novels, it contains disturbing descriptions of child abuse.
Document 6: Yale University: Other examples of the Gothic (also called neo-Gothic and collegiate Gothic) style are on Old Campus by such architects as Henry Austin, Charles C. Haight and Russell Sturgis. Several are associated with members of the Vanderbilt family, including Vanderbilt Hall, Phelps Hall, St. Anthony Hall (a commission for member Frederick William Vanderbilt), the Mason, Sloane and Osborn laboratories, dormitories for the Sheffield Scientific School (the engineering and sciences school at Yale until 1956) and elements of Silliman College, the largest residential college.

The Yale University Art Gallery, the country's first university-affiliated art museum, contains more than 180,000 works, including Old Masters and important collections of modern art, in the Swartout and Kahn buildings. The latter, Louis Kahn's first large-scale American work (1953), was renovated and reopened in December 2006. The Yale Center for British Art, the largest collection of British art outside of the UK, grew from a gift of Paul Mellon and is housed in another Kahn-designed building.
Document 9: Great Expectations: Great Expectations is the thirteenth novel by Charles Dickens and his penultimate completed novel: a bildungsroman that depicts the personal growth and personal development of an orphan nicknamed Pip. It is Dickens's second novel, after David Copperfield, to be fully narrated in the first person. The novel was first published as a serial in Dickens's weekly periodical All the Year Round, from 1 December 1860 to August 1861. In October 1861, Chapman and Hall published the novel in three volumes.

Yale also owns and has restored many noteworthy 19th-century mansions along Hillhouse Avenue, which was considered the most beautiful street in America by Charles Dickens when he visited the United States in the 1840s. In 2011, Travel+Leisure listed the Yale campus as one of the most beautiful in the United States.
Document 12: Yale University: Yale's secret society buildings (some of which are called "tombs") were built both to be private yet unmistakable. A diversity of architectural styles is represented: Berzelius, Donn Barber in an austere cube with classical detailing (erected in 1908 or 1910); Book and Snake, Louis R. Metcalfe in a Greek Ionic style (erected in 1901); Elihu, architect unknown but built in a Colonial style (constructed on an early 17th-century foundation although the building is from the 18th century); Mace and Chain, in a late colonial, early Victorian style (built in 1823). Interior moulding is said to have belonged to Benedict Arnold; Manuscript Society, King Lui-Wu with Dan Kniley responsible for landscaping and Josef Albers for the brickwork intaglio mural. Building constructed in a mid-century modern style; Scroll and Key, Richard Morris Hunt in a Moorish- or Islamic-inspired Beaux-Arts style (erected 1869–70); Skull and Bones, possibly Alexander Jackson Davis or Henry Austin in an Egypto-Doric style utilizing Brownstone (in 1856 the first wing was completed, in 1903 the second wing, 1911 the Neo-Gothic towers in rear garden were completed); St. Elmo, (former tomb) Kenneth M. Murchison, 1912, designs inspired by Elizabethan manor. Current location, brick colonial; Shabtai, 1882, the Anderson Mansion built in the Second Empire architectural style; and Wolf's Head, Bertram Grosvenor Goodhue (erected 1923-4).
Document 13: Charles Dickens: Dickens's literary success began with the 1836 serial publication of The Pickwick Papers. Within a few years he had become an international literary celebrity, famous for his humour, satire, and keen observation of character and society. His novels, most published in monthly or weekly instalments, pioneered the serial publication of narrative fiction, which became the dominant Victorian mode for novel publication. Cliffhanger endings in his serial publications kept readers in suspense. The instalment format allowed Dickens to evaluate his audience's reaction, and he often modified his plot and character development based on such feedback. For example, when his wife's chiropodist expressed distress at the way Miss Mowcher in David Copperfield seemed to reflect her disabilities, Dickens improved the character with positive features. His plots were carefully constructed, and he often wove elements from topical events into his narratives. Masses of the illiterate poor chipped in ha'pennies to have each new monthly episode read to them, opening up and inspiring a new class of readers.
Document 14: New Haven, Connecticut: Many historical sites exist throughout the city, including 59 properties listed on the National Register of Historic Places. Of these, nine are among the 60 U.S. National Historic Landmarks in Connecticut. The New Haven Green, one of the National Historic Landmarks, was formed in 1638, and is home to three 19th-century churches. Below one of the churches (referred to as the Center Church on-the-Green) lies a 17th-century crypt, which is open to visitors. Some of the more famous burials include the first wife of Benedict Arnold and the aunt and grandmother of President Rutherford B. Hayes; Hayes visited the crypt while President in 1880. The Old Campus of Yale University is located next to the Green, and includes Connecticut Hall, Yale's oldest building and a National Historic Landmark. The Hillhouse Avenue area, which is listed on the National Register of Historic Places and is also a part of Yale's campus, has been called a walkable museum, due to its 19th-century mansions and street scape; Charles Dickens is said to have called Hillhouse Avenue "the most beautiful street in America" when visiting the city in 1868.
Document 15: Barnaby Rudge: "Barnaby Rudge" was the fifth of Dickens' novels to be published. It had initially been planned to appear as his first, but changes of publisher led to many delays, and it first appeared in serial form in the "Clock" from February to November 1841.
