Incidentally, I was asked a few months ago about incorporating Open
Library and/or Internet Archive material into a service I (barely)
maintain called Ockham Alert. I told them I would be happy to do so,
but since Ockham Alert relies on OAI date ranges, and their date
ranges did not work, I was unable to oblige them. I suppose the date
issue with their OAI implementation is a known issue.
