The Society for the Diffusion of Useful Knowledge was established in 1828, with Henry Brougham as Chairman. Mr. Murray subscribed £10 to this society, and agreed to publish their "Library of Entertaining Knowledge." Shortly afterwards, however, he withdrew from this undertaking, which was transferred to Mr. Knight, and reverted to his own proposed publication of cheap works.

The first volume of "The Family Library" appeared in April 1829. Murray sent a copy to Charles Knight, who returned him the first volume of the "Library of Entertaining Knowledge."

Mr. Charles Knight to John Murray.

"We each launch our vessels on the same day, and I most earnestly hope that both will succeed, for good must come of that success. We have plenty of sea-room and need never run foul of each other. My belief is that, in a very few years, scarcely any other description of books will be published, and in that case we that are first in the field may hope to win the race."

Mr. Murray's intention was to include in the Library works on a variety of subjects, including History, Biography, Voyages and Travels, Natural History, Science, and general literature. They were to be written by the best-known authors of the day—Sir Walter Scott, Southey, Milman, Lockhart, Washington Irving, Barrow, Allan Cunningham, Dr. Brewster, Captain Head, G.R. Gleig, Palgrave, and others. The collection was headed by an admirable "Life of Napoleon," by J.G. Lockhart, partly condensed from Scott's "Life of Napoleon Bonaparte," and illustrated by George Cruikshank. When Lockhart was first invited to undertake this biography he consulted Sir Walter Scott as to the propriety of his doing so. Sir Walter replied:

"Your scruples about doing an epitome of the 'Life of Boney' for the Family Library that is to be, are a great deal over delicate. My book in nine thick volumes can never fill the place which our friend Murray wants you to fill, and which if you don't some one else will right soon. Moreover, you took much pains in helping me when I was beginning my task, and I afterwards greatly regretted that Constable had no means of remunerating you, as no doubt he intended when you were giving him so much good advice in laying down his grand plans about the Miscellany. By all means do what the Emperor [Footnote: From the time of his removal to Albemarle Street, Mr. Murray was universally known among "the Trade" as "The Emperor of the West.">[ asks. He is what the Emperor Napoleon was not, much a gentleman, and knowing our footing in all things, would not have proposed anything that ought to have excited scruples on your side." [Footnote: Lockhart's "Life of Scott.">[

The book met with a warm reception from the public, and went through many editions.

Among other works published in "The Family Library" was the Rev. H.H. Milman's "History of the Jews," in three vols., which occasioned much adverse criticism and controversy. It is difficult for us who live in such different times to understand or account for the tempest of disapprobation with which a work, which now appears so innocent, was greeted, or the obloquy with which its author was assailed. The "History of the Jews" was pronounced unsound; it was alleged that the miracles had been too summarily disposed of; Abraham was referred to as an Arab sheik, and Jewish history was too sacred to be submitted to the laws of ordinary investigation. Hence Milman was preached against, from Sunday to Sunday, from the University and other pulpits. Even Mr. Sharon Turner expostulated with Mr. Murray as to the publication of the book. He said he had seen it in the window of Carlile, the infidel bookseller, "as if he thought it suited his purpose." The following letter is interesting as indicating what the Jews themselves thought of the history.
