I made a point of noting the reviews, essays, books, translations etc that Nabokov liked or disliked. It is of course entertaining, not quite as beautiful as Letters to Vera ( it shouldn't be) and informative. The Lolita publication business and Nabokov's ecstasy over Ada's cover and binding ( "a sumptuous volume"), the final dimming letters ( time dimming, not cerebral-space) are all valuable for the Nabokov reader.
