Once you’ve read the essays in Otherwise Known as the Human Condition, there is little need to also buy Working the Room, but I am a Geoff Dyer completist.
Additional are essays on photographers Larry Burrows, Jacob Holdt, Martin Parr and Trent Parke, and explorations of: D. H. Lawrence: Lady Chatterley’s Lover, Tobias Wolff: Old School, Richard Ford: The Lay of the Land, and Alan Hollinghurst: The Line of Beauty.
The Hollinghurst essay stood out, convincing me that I ought to read The Line of Beauty:
There are literally thousands of impeccably nuanced touches like this in the novel. Hollinghurst, in James’ own words, is one on whom nothing is lost.
