First, you should appeal to these thrift shops to use a pencil. Some thrift shops I haunt will pencil in the price on the inside cover, then to thwart repricers, pencil it in again on a different page. I've never had any luck removing grease pencil and have ended up smearing it. I suggest you look up the Library of Congress on the web and email them for advice if they have nothing listed for book preservation.

I'd like to remove this safely. Can someone point me to the right place to find this sort of information? Thanks.
