A typical page in this book contains 3 columns: International English Name, Scientific Name, and Region(s), with one line per species. Birds are grouped by order and family.
One of the best things about this book is that it comes with a CD with an Excel spreadsheet containing all of the birds in the book. My "life list" currently consists of little notes written in a bunch of field guides (all written in various languages, depending on where in the world I was). I plan to use this spreadsheet to consolidate and organize all of the data I've collected so far about the birds I have seen around the world, and I find it helpful to have consistent English names for the birds (rather than the local names in the field guides).
