It gets its metadata in different ways. the strange thing about this example however, is that in the metadata of this specific book at Google the correct ISBN is shown !! (well I presume ii ts the correct isbn (ISBN 0851993575) However, it can not be found with a query on this ISBN, but it is found on an incorrect isbn:0851992544 Peter -----Original Message----- From: Code for Libraries [mailto:[log in to unmask]] On Behalf Of Karen Coyle Sent: dinsdag 18 maart 2008 1:16 To: [log in to unmask] Subject: Re: [CODE4LIB] Free covers from Google I've seen this frequently in publisher data -- especially from small publishers. Their metadata goes out with the same ISBN for every book they publish. I don't know if this gets corrected later (I assume it does to make the ordering process work). My guess is that they send out the first metadata before they've gotten an ISBN assigned to the book, so they just re-use one because the ISBN is required. In the few examples I saw, the Amazon records had the correct ISBN, but the Library of Congress records had the wrong ISBN that was originally (presumably) transmitted. The publishers have an incentive to keep Amazon up to date and correct (and perhaps also the bookstore databases and Books in Print). The real question is: where is Google getting its metadata, and what is it doing with metadata from different sources for the same item? kc Boheemen, Peter van wrote: > Hmm, just found an example where Google clearly does something wrong: > Look at: http://library.wur.nl/WebQuery/catalog/lang/948125 > > It shows a cover and links to the wrong book !!! > The look up is based on isbn 0851992544, but this book has got isbn 0851993575 and this is also clearly stated in the Google book info !! > > If you just go to Google book search and type isbn:0851992544 in the search box. You will find 4 titles !! of which the first one is the one I get from the service I use. The second one is the correct one. If you type isbn:0851993575 you even get 6 hits and they all seem to share this ISBN !!! > > I don't know if it does a lot of these mistakes.
