I used to do it all in one doc and switch document class as you suggest. However, I found the presentation often needs tweaked to get the article to look right and the child document approach allows easier regular compilation to check that it looks OK. But I agree using branches looks a promising approach Certainly its going to be better than PowerPoint, I will give it a go. Thanks, Graham
