Consider the following passage:
The first sound in the mornings was the clumping of the mill-girls’ clogs down the cobbled street. Earlier than that, I suppose, there were factory whistles which I was never awake to hear. There were generally four of us in the bedroom, and a beastly place it was, with that denied impermanent look of rooms that are not serving their rightful purpose. One afternoon, early in October, I was invited to black coffee at Fritz Wendel’s flat.  Fritz always invited you to ‘Black coffee’ with emphasis on the black. He was very proud of his coffee. People used to say that  it was the strongest in Berlin. Fritz himself was dressed in his usual coffee-party costume–a very thick white yachting sweater and very light blue flannel trousers.
Was it written by George Orwell or Christopher Isherwood? In fact, both. Its part of a longer passage composed by Cyril Connolly, a noted literary critic, whose name is now lost to posterity. The longer passage melds Orwell with Isherwood and Hemingway to produce something coherent (it appears in Connolly’s semi-autobiographical Enemies of Promise). With current technologies one wonders if one might form an entire novel using only sentences that have appeared in various other books.
What was Connolly’s purpose for sampling in this way? It was to make a point about competition for market share in literature. Best to let him relate it in his own words:
This, then, is the penalty for writing for the masses. As the writer goes out to meet them half-way he is joined by other writers going out to meet them half-way and they merge into the same creature-the talkie journalist, the advertising, lecturing, popular novelist.
