My rating: 4 of 5 stars
If you are new to Subversion this is a decent read discussing the main ways you will use the repository and most likely the tools you’ll be using to do so.
If you’ve been using Subversion for a while it can be useful just to cement how Subversion handles things like deletions/moves/renaming. There are also some advanced topics covered like patch files and repository hooks.
All in all a good book. It delivers good information in easily digested chunks, and offers a good place to start on more advanced topics.
