Did you know that Amazon offers a facility to make corrections to its catalog? Somewhere in the past few months someone mentioned this to me and I tried it out. (Unfortunately, it has been long enough now that I’ve forgotten who told me; if you are the one, please fess up in this post’s comments section. It was Ron Murray from the Library of Congress. Thanks, Ron!) And it works! Is this a model for crowdsourced corrections to library data?
