Unlike the book Couplan the format of this book is ideal to go on hiking. I gave him a small plastic box not too much damaged. Regarding the content, there is the essential, but it lacks still not a lot of cash (horseradish, saxifrage, wild rhubarb, lime, campion, currency of the pope, thistle ... And it's hard to go on a hike with several books. Some lack representation readability, but overall, it's pretty decent. In short I recommend, but for me a second a little more complete edition would be welcome
