Ed ~ The Collins Pocket Guide is a very handy quick reference to the night sky. The layout is simple and easy to navigate; with each constellation guide page having a clear chart, and information and a few accompanying highlights on the opposite page. The book is appropriate for both Northern and Southern hemispheres.
It will fit into your coat pocket and so is ideal for outdoor use, be it naked eye, telescope or binocular observing. The paperback sized version is a lot more useful than smaller star guides. That, and given the price, i would thoroughly recommend this version. It goes without saying that this one book is what i personally use at the eyepiece.
The fourth edition renamed 'Collins Stars and Planets Guide' can be picked up for ~ £10.00
