Add Wikipedia as source

...at least when an article lists an ISBN, a la http://en.m.wikipedia.org/wiki/Dark_Age_Ahead

Sounds intriguing, but challenging:

• It may not be very satisfying to use if it only works on a small fraction of pages.
• What do we do about multiple ISBNs on the same page? I suppose we could have a list for people to pick from... that UI would work for Amazon find results and whatnot as well, but of course it wouldn't be trivial to create.
• Are ISBNs easy to scrape off of Wikipedia? The one on that page is in an anchor tag with a title attribute of "Special:BookSources/1-4000-6232-2"... perhaps that's a consistent feature (the BookSources, not the number of course).

Incidentally, if you click on that link, it goes to http://en.wikipedia.org/wiki/Special:BookSources/1-4000-6232-2 which is basically Wikipedia's own Interchange. It would probably be quite straightforward to make Interchange work on that page... I wonder if there are any kind of fancy symbiotic things we could do with that page.

These are all good points. Thank you for the reality check. I think I'll reframe this as "pick over wikipedia's BookSources exchange and see if we can play nicely with it".

Sounds good :-)
