The service is not ideal either though. E.g. [ISBN 9781291708004](http://www.lulu.com/shop/ruth-finnegan/melody-of-the-earth-a-garden-anthology/hardcover/product-21420641.html), which is published by Callender Press, but [WorldCat](http://xisbn.worldcat.org/webservices/xid/isbn/9781291708004?method=hyphen&format=xml) returns "Lulu Com" as the publisher (since they issue ISBNs in very small chunks). This would be picked up correctly using the Lulu translator though (I'm not entirely certain it would work in connectors and definitely not in Bookmarklet)
