Corel Draw is a very large application. Learning to use it effectively even if only to enhance promotional material needs more than a suck it and see approach. I think this book is an excellent way for the occasional user (e.g. the person who is not a commercial artist but wants to prepare their own promotional material) to get some basic efficiency in using Corel Draw.
One, to my mind, bizarre feature is the CD that comes with the book. This not only includes a try out versions of Corel Draw 5 and 8 but also a version of Adobe's Photoshop 5 (with external use of the clipboard, saving and printing disabled). The reason I find this odd is that Photoshop is a competitor to Corel Draw. I suppose this is a good indication that the authors are independent. I warn you that once you have tried Photoshop you may never again be happy with Corel Draw - however getting a full copy of Photoshop will not be cheap.
