Readers of this website may be a little put off by the £35 price tag for this book. In which case they may like to request the book via their local library service. I have just spent a few minutes online requesting this book on the Hertfordshire Library Service. The cost is minimal - 50p for the reservation plus a possible £3 if they obtain the book through an inter-library loan.

The results are two-fold. I get to read this book at low cost, and the library get to put useful books on their shelves, if they decide to add this book to their stock. I recommend others to try this tip.
