This is a rather nice anthology of Georges Perec's nonfiction writing. As you'd perhaps expect if you've read anything else by Perec, it covers a fairly random selection of subjects -- the concept of "spaces", how and why we read, the buildings on a street, the contents of Perec's desk -- in a typically eccentric fashion. It's not as strong as, say, "Life A User's Manual", but it's interesting to see Perec examining reality in the same way as his fictional worlds. Recommended if you've enjoyed Perec's other work.
