Having no previous experience making cocktails it's hard to judge this book against another, however it seems a pretty decent catalogue of cocktail recipes. There are pictures of about 50% of the cocktails, with snippets of information about some of the more exotic liqueurs or brands of spirits, in addition to the cocktail basics and equipment. Comparing the recipes to those on the internet it seems reasonably accurate.
It groups the cocktails by their main constituent part (i.e. chapters on whisky, rum, vodka, gin, brandy, and tequila cocktails) rather than grouping them by their style (long, short etc), which has advantages and disadvantages. Ideally, in my opinion, a cocktail book would have a glossary showing recipes grouped by their main constituent parts in addition to their style, and then perhaps showing simple cocktails that get increasingly more complex. With 600 odd recipes it can be quite frustrating looking through 50 or so drinks before you find one that you actually have enough of the ingredients to make. Maybe having a chapter for the classics would be an idea, and also the inclusion of the Long Island Ice Tea, which staggeringly, is absent from this collection - my favourite cocktail!
Despite this however, it is a good place to start. There are some poor books in this category, and I imagine that this will be good for both the beginner or for the person looking to expand their repertoire.
