I came in late to this discussion and while I'm supportive of removing links to infringing sites ... was there any value in the link? I mean were you pointing out a particular book/page that helps with the original problem? If so, can we please have that citation (and with the isbn linkage)? If there was no value in the link, can you annotate the editing to "removed spurious/unhelpful link to copyrighted material."
