Query: Not up to par

I've been reading "Linux Security Cookbook". I fully understand the goal of this book is to provide lots of little bits of wisdom, not a full fledged security book. I think that's pretty cool. However I'm finding that a lot of the recipies, if you will, are either not well explained, the equivalent of reading a real cookbook witohut knowing what it means ot 'fold the blueberries into the batter'. They could easily have spent more time explaining things so we didn't need to go read/re-reading the man pages just to understand the book.
