Query: Shallow and brief, but better than nothing

I suppose that someone who knew absolutely NOTHING about German culture would find this book interesting and useful. But, if you already know a little bit and want to learn more (like me) you will likely be disappointed. Others have pointed out that each topic is covered briefly, and in my opinion, that's usually EXTREMELY briefly. I find the alphabetical organization of topics unhelpful, and would prefer to have similar subjects located together. I often had to guess several times to see which word the author would use to alphabetize a given topic. If you're looking for more than a quick-and-dirty introduction to German culture, skip this book and read "Culture Shock! Germany" instead.
