Hi. I've got the Robert Peterson book, so I've just compared chapter headings and one of the chapters, and they are identical.
I also have "Astral Travel for Beginners" by Richard Webster and the Astral Projection Workbook by JH Brennan, and they are both pretty good overviews of the subject with various methods. Why not check your local library first, before you buy any.
I actually prefer reading about the author's own experiences, because they usually have instructions how they achieved it. It seems to take OBEs out of the realm of theory and make them more a practical reality. But each to their own.
