This is worth a mention: Mikita Brottman’s The Solitary Vice: Against Reading. I read about it in Kevin Arthur’s Question Technology blog. The book begins by questioning whether reading is necessarily good for you, and continues as a memoir of reading in different genres. Brottman’s own site links to a number of reviews.
Reading is a good subject.
I haven’t looked at the book yet, but Brottman has advanced degrees in both literature and psychoanalytic theory, which I think would give her an interesting perspective on the subject.
