For me, the links work. However, the ones to the Google book, work, but I have to scroll through to get to the correct page - the link automatically sends me to page 167 and not page 168.
This could be why you're receiving the 966 error. Maybe a direct link to page 168? I would think that would fix the error.
False errors do occur. Personally, I wouldn't mark it as a false error until attempts have been made to fix it.
