On the proliferation of ISBNs - via Laura Dawson
One key bit of data about a book is the ISBN, the number assigned to it for lookup purposes. I hate to call it metadata, but there it is; it's data too.
The beginning of the ISBN era marks the time where books can be treated as commodities, as unambiguously tagged stock items that can be kept track of as precisely as gum or soap. And because every book needs one to go on the shelf, some publishers have taken the step to make every (minor) variant of a given work have its own unique ISBN. This could even mean that the dark red cover of the 3d edition has a different ISBN than the light red cover of the 3d edition. Useful for record keeping and inventory, but it starts to make a mess of book finding systems where the ISBN is often the only unique identifier that lets you move from one system to another to find the "same thing".
Laura Dawson notes this on read20-l - her comments from inside a large publisher are instructive.
Maintaining the metadata associated with each one of these ISBNs is incredible. Say you've got a Spanish textbook. Then you've got the e-version of it in three different formats (VitalSource, Quia, and
CourseSmart). Then you've got the print lab manual and the print workbook. Then you've got the e-versions of these. Plus you've got downloadable language labs that you can port into your iPod. You've got
instructional animations that are available as a separate product that you can put on your iPod as well. That's 14 related ISBNs with associated metadata attached to each one. Then if you need to customize
any of these for a particular state university adoption...It's rather like having a very large extended family and having to keep track of birthdays, anniversaries, graduations, who's in trouble at school, who needs new clothes, what the babysitting schedule is, who is
getting a divorce, and that your niece is learning-disabled and your brother has to sue the school district every year just to get her the services she needs....In other words the more ISBNs you have, the more crucial accurate metadata becomes, because otherwise how the hell are you going to keep your products straight? And I think this is in large part what
publishers object to. They have a lot of frustration in keeping up with the metadata explosion that goes on with these splintered, fragmented, related products.The mistake is in thinking that fewer ISBNs means less data administration. Your products still need to be sold, even if we could come up with a different way of identifying them - just as your
husband's second cousin will still need a new baby gift even if you can't for the life of you remember her name.No, really. The more products you get involved with, the more metadata you have to keep track of. And that's just a cost of doing business.
Laura's blog is a worthwhile read for perspectives from the publishing
industry, especially on book industry standards.
