This first edition has numerous code errors in examples, and basic command listings. It is a total waste of time and money trudging through misprints. This book is 1month old and is already useless. For example if you followed the instructions in Chapter 2 as to how to create a repository, then followed the instructions on how to checkout you would Fail right away because the example command is missing a "/".... Small but high impact misprint!
If you're serious about stepping up to subversion, this book is licensed under GPL and as such can be downloaded for free from svnbook.red-bean.com.
My only regret with subversion so far is spending $25 to find out I could have gotten a much more error free version for nothing!
