PositiveShelf Awareness...[a] fascinating account ... Weschler...serves up a potpourri of conversations, diary entries, interviews, letters and reportage to paint a vibrant portrait of his friend\'s fully engaged, at times frenetic, life. Though it inevitably covers some of the same ground as Sacks\'s own 2015 memoir...this blend of journalistic objectivity and subjective engagement in Sacks\'s daily life enlarges and complements the neurologist\'s self-portrait ... But for all Weschler\'s deep affection for Sacks, he doesn\'t shy away from the controversies that at times swirled around his subject\'s life and work ... As Lawrence Weschler concedes, with obvious regret, someday a person who \'will have to be a lot younger than I am now\' is going to produce a full-length biography of Oliver Sacks. In doing so, that writer will be in Weschler\'s debt for the wealth of valuable source material his book provides.
