Am I missing something? Where are all these stars coming from? Only 50% of the time does this book address my questions. The book has a ton of information but is almost unusable for the average researcher. Be sure to review the book in detail before purchasing to verify that it has what you're looking for. The glossary is virtually useless. You'll spend a lot of time searching for your answers. Bad usability.
