I'm glad i only borrowed this book from a local library and did not buy it. Whilst some readers may find it very useful, I found it too 'heavy' a read. It takes quite a serious tone, and as I am not a professional author etc, i didn't find it a hugely beneficial read. I would recommend something like Who's Whose, as I certainly found Who's Whose a much more light-hearted read, with more interesting information. This book however i recommend to only serious writers and people writing for worldwide audiences.
