My husband and I are currently living in a lovely little area that has a wonderful library, which, as you can imagine, we have been taking fully advantage of.  The benefit of using a library versus a bookstore–other than the savings!–is that older books are as clearly marked and accessible as newer books.  Borna picked up such a book recently is When Strangers Cooperate: Using Social Conventions to Govern Ourselves by David W. Brown, which I was surprised he rated 2 of 5 stars.  But as he explains in his review, the title, full of promise, comes short: “It feels like something is missing though, as there isn’t really much of a conclusion (a short paragraph at the end) nor much on how to actually go about with it. The suggestion is that conventions are good, and that there should be more of them. Sure, sounds good, but not worth writing and reading a book about.”  Read the full review here.
