Query: I returned it immediately

It delivered it to me from Amazon.ca this afternoon together with the 2nd edition of "Software Configuration Management Strategies and IBM Rational ClearCase". I can still keep the later but I have to return this one immediately.I can't even find the keywords of "mainline" and "composite baseline" from the index. Definitely I've brought a wrong book about ClearCase.
