You may be confused by a few instances in the book where there is reference to "WSS versus SharePoint".
To avoid to much future confusion, instances such as those above 'should' read "WSS versus MOSS". During a very rigorous editing and publishing process, sometimes these things can slip by which in this case, it did.
Just to let people know, we are aware of it's existence and we have taken the measure to report, and correct future prints.
For those that might remain confused on the terminology:
MOSS refers to Microsoft Office SharePoint Server 2007 which is the enterprise (all bells and whistles) version of SharePoint Products and Technologies. This includes things such as Enterprise Search, and The Business Data Catalog or Excel and Forms Services.
WSS refers to Windows SharePoint Services (now 3.0) which is a free download and contains the core components of lists, libraries etc.
When referring to these two collectively, one can use SharePoint 2007.
I hope that helps!
