As others have commented, this collection is uneven but Lethem has done an admirable job in assembling a diverse collection of modern authors, mainly in the realm of fiction. Unfortunately, some of the approaches and themes are repetitious, leading one to confuse many of the plots with each other (how many times must a man wake up and wonder where he is and why he has no memory of his past?). However, some stand-out pieces from JL Borges, LJ Davis, Philip K Dick, Julio Cortazar and Robert Sheckley demonstrate that a simple theme can lead to surprisingly disparate approaches. Overall a worthwhile purchase for the 400 pages of mind-bending literature it contains.
