Example Input: Passage: After school, Greg settled into a life of steady productivity, while living on the proceeds of his shares of The Economist. Working in close association with A. H. Bullen, he produced Pastoral Poetry and Pastoral Drama (1906), the first edited version of the account books of Philip Henslowe (1906–8) and the papers of Edward Alleyn. The latter two works provided him with a knowledge of Renaissance theatrical conditions perhaps rivaled only by E. K. Chambers, and this knowledge he applied to the publications of the Malone Society, which he served as general editor between 1906 and 1939. He served as Librarian of Trinity College, 1907–13, resigning after his marriage to his cousin Elizabeth Gaskell. As an independent scholar, Greg produced editions of The Merry Wives of Windsor (1910), Robert Greene's Orlando Furioso and George Peele's The Battle of Alcazar (published together, 1923), and Sir Thomas More (1911). He returned to specific editing with work on Doctor Faustus (1950). Greg also wrote on the material conditions of Renaissance theater and publishing; his work in this regard includes Dramatic Documents from the Elizabethan Playhouses (1931) and English Literary Autographs, 1550–1650 (1932). The Variants in the First Quarto of King Lear (1940) offered a careful examination of this printing. He also wrote hundreds of reviews, including a notably caustic rejection of J. Churton Collins's 1905 Oxford edition of Robert Greene.

Example Input: Passage: At the quayside, Marshal Foch saluted the casket before it was carried up the gangway of the destroyer, , and piped aboard with an admiral's call. The Verdun slipped anchor just before noon and was joined by an escort of six battleships. As the flotilla carrying the casket closed on Dover Castle it received a 19-gun Field Marshal's salute. It was landed at Dover Marine Railway Station at the Western Docks on 10 November. The body of the Unknown Warrior was carried to London in South Eastern and Chatham Railway General Utility Van No.132, which had previously carried the bodies of Edith Cavell and Charles Fryatt. The van has been preserved by the Kent and East Sussex Railway. The train went to Victoria Station, where it arrived at platform 8 at 8.32 pm that evening and remained overnight. ( marks the site: every year on 10 November, a small Remembrance service, organised by The Western Front Association, takes place between platforms 8 and 9.)

Steedman became an editor of the North-Western Democrat and Toledo Times newspaper and a major general of the 5th Division in the Ohio State Militia in 1857, holding both positions until the beginning of the American Civil War in 1861. From 1856 to 1860, he also worked as a printer for the United States Congress.
