I forgot to tell you that I got the first 100 pages of my book printed. It arrived from the US the other day. I was surprised by the quality of the job. I've learned something about preparing covers - the title on the spine should read with the baseline at towards the back of the book. Other than that (and the fact that I haven't been able to figure out how InDesign automatically numbers pages (any advice gratefully received). All in all, well pleased. Just like a bought one. I'll let you know when you can order a copy.
It's like you got yesterday, today and tomorrow, all in the same room. There's no telling what can happen.
