A good source for you to consult as a start is William H. Hutt's THE KEYNESIAN EPISODE: A REASSESSMENT. Indianapolis: Liberty Press, 1979. (This is a revision of Hutt's KEYNESIANISM: RETROSPECT AND PROSPECT. Chicago: Henry Regnery, 1963.) Chapter 16 on "The Multiplier" directly relates the banking multiplier to the Keynesian one and ties Keynes to F.W.Crick's banking multiplier explanation through Keynes's TREATISE ON MONEY.
