The web magazine PLANetizen, which I am just beginning to read and enjoy has a yearly list of best books on Urban topics. I've read at least one from each year and can tell you that I've liked them so far. I'm going to work my way through the lists. Here is the list for 2005. The Jane Jacobs is really good.
ps. if you're wondering why I always post photos, it's because a) I like them and b) BU blocked access to blogger but not flickr.
