What I've done in my very rough demo is to say something like
"Full text available", "Parts of text available" and "Additional information available".  (Not exactly, but it's not worth the time to look it up).  The general consensus around here seems to be even the minimal records tend to have useful information, more so than if Google was just repeating the catalog entry.  The links don't even show up at all if there is no google information.
