Read on Kindle, or rather partly read. This guy put the hours in, and there's plenty of interesting stuff. Unfortunately there's also plenty of not that interesting stuff, and they blend into each other after a bit. The A-Z section, which starts about 73% in (I said I read it on Kindle), is probably the most worth a bit of leafing through. Not the best beach read, although you could always play around with reviving some fun old slang.
