In 1910, he published a history, "China Under the Empress Dowager" and in 1914, "Annals and Memoirs of the Court of Peking", both with British journalist J.O.P. Bland. With these books he established his reputation as an oriental scholar. In 1913, Backhouse began to donate a great many Chinese manuscripts to the Bodleian Library, hoping to receive a professorship in return. This endeavour was ultimately unsuccessful. He delivered a total of eight tons of manuscripts to the Bodleian between 1913 and 1923. The provenance of several of the manuscripts was later cast into serious doubt. Nevertheless, he donated over 17,000 items, some of which "were a real treasure", including half a dozen volumes of the rare Yongle Encyclopedia of the early 15th century. The Library describes the gift: "The acquisition of the Backhouse collection, one of the finest and most generous gifts in the Library's history, between 1913 and 1922, greatly enriched the Bodleian's Chinese collections."
