This is a great book for someone who wants a starting point for identifying wildlife, whether in the garden or out and about. It covers a wide range of categories - trees, wildflowers, insects, birds, etc, etc. Obviously in a book this size it can't be comprehensive, but the coverage is fantastic for a single book. I've found that as my interest has deepened I've bought a few more specialist books, but I didn't really know what areas I'd become particularly interested in until I'd used a more general book like this, and I still like to carry it with me on a walk or have it to hand if I'm in the garden, while I have some more specialist books at home. The pictures are all photos, which are mostly clear, but I think drawings can make identification easier and I did find some wild flowers difficult to identify from the photos in this book, but when that happens I normally take photos and then double check with other books or internet when I get home. Its worth knowing that, despite being called a "pocket" guide, this is quite a heavy volume, a couple of centimetres thick and weights around 700g, which might be off putting for some people if you are looking for something lightweight, but I find it fine for carrying in a backpack. On the whole I would recommend this as a good general nature identification guide, either for someone starting out in this hobby, or for someone with a general interest, and it's good value for money too.
