> the link above i cant dowenload it using httrack?> can any one help me?
It sems that the link can not be accessed by external 
connections ("Certain resources are restricted by 
subscription and licensing agreements to UC faculty.." 
message) ; or can not be accessed without authentication. 
In this case you will probably have to use the "Add 
URL"/"Capture URL" feature from httrack to capture the 
authentication form (first erase all your cookies, to get 
the login screen).
