I've looked through all the other books on knots (and/or fishing knots), and even own some of them. This book is the hands-down winner. First, it has ALL the knots. Second, it's very specific about how to tie them, including how many wraps for different situations, and which side the tag end should come through, etc. The only problem with the book is that it can be a little hard for a beginner to figure out what basic set of knots s/he needs for a particular type of fishing (e.g., fly fishing). Although the book makes an effort at this, their suggestions don't jibe with what I've learned in the field and are a bit too complicated.
