I am a designer-publisher and work with many self-publish clients. When I realised that there was a later version than my previous book, I had no hesitation in updating. Also passed on my previous version to one of my favoured clients (author and poet) and she is looking forward to using it. I have been using the Style Manual since 1996, and consider it my publishing Bible. Thanks to Booktopia, I did not have to wait long for the book to arrive. Now I just need a few hours to get used to the new layout.
