'Did Melanie Klein ever think that 50 years after her death her ideas would be spreading world-wide in such a fruitful and productive way? In one sense she would be surprised, but in another, I think she might have regarded it as just to be expected. She had a very high regard for her own work, and enormous confidence that she was on to something new. At the same time she was fatefully resigned to being misunderstood and rejected - just as Freud had been, of course. But now, here is the evidence of her success: two thousand plus references, and climbing. Klein's ideas are truly international now, and perhaps wherever Freud is there Klein shall be, to adapt a well-known phrase. Of course this is in the context of other schools which also spread slipperily across the globe, thanks now to the web. But Harry Karnac's bibliography is a proper published document, and is of immense potential use for clinicians, students, and researchers. Its embrace is much wider than Kleinian texts on PEPWeb, and it is a natural companion to that database. It is also a companion to Harry's previous bibliographies of Winnicott and Bion.' - Bob Hinshelwood, from the Foreword
