This is a very useful book which is excellent to have for reference. It contains very clear information on the British Production Process in relation to the work of a Stage Manager. It is also one of the most recent in it's subject field making the information very relevent and up to date. It has lots of helpful hints that I personally have used on several occasions. The book has clear diagrams and each step of the Production Process is explained in detail.
The book is very accessable and easy to read with it's clearly laid out sections, making it easy to find the information that you need quickly. There is also a glossery of Theatre terms which is also useful for reference.
All in all a good book which you will use time and time again.
