- ^ Imminent termination of the partnership and succession by Routledge was reported in "Literary Gossip", The London Review, 17 June 1865, p. 646. "On the 30th of the present month the partnership hitherto subsisting between Mr. George Routledge, Mr. F. Warne, and Mr. R. W. Routledge, will terminate. After that date, business will be carried on by the Messrs. Routledge under the style and title of George Routledge & Sons, who will receive all accounts due to, and meet all claims against, the present firm."
The next weekly issue of The Athenaeum, no. 1965, 24 June 1865, carried two advertisements by Frederick Warne & Co. and one by George Routledge & Sons (its "List of New Books", p. 855). Warne announced a new arrangement as the exclusive seller of books published by S. O. Beeton (p. 834) and provided a double list of books (p. 835): "S. O. Beeton's Publications" and "Works: Formerly published by Routledge, Warne & Routledge, now the property of Frederick Warne & Co." Two weeks later Warne listed its own "New Publications", The Athenaeum, no. 1967, 8 July 1865, p. 37.
