Today (Sunday November 19th) the Sunday Times advertises that it is 
giving away a copy of Encyclopaedia Brittanic on CD.

Is this the full text of the hard copy version?

If it is the full text then is access restricted in any way?  

For example:  being time limited, or shortened articles, or being just a 
front end to the Brittanica website, or needing subscription charges at 
a later date, etc.
