Interesting! This, in a nutshell, is why projects to collect all the world's bibliographic data face a hard challenge. > Why am I posting this to Foundation-l? > > Well, one of the things it reveals is the difficulty of answering this > question and I hope that it has some relation to Wikimedia projects; > in particular, I didn't know that multiple books (entirely unrelated > books) have shared ISBNs.

What is a much, much, much bigger problem is the issue of serials holdings: "serials" are normally taken to be things like magazines and journals, but in library land also might refer to, say, book series, or government reports that are published with serial numbers. All sorts of stuff, in other words, and it's cataloged and referred to in all sorts of ways, which makes it tough for people looking for good unique identifiers (or trying to figure out what counts as "a book"). > And I also thought that Google's attempt to catologue all books was > parallel to our goal of... well, I'm not sure that we ever say we're > attempting to catalogue ALL knowledge... but we seem to be making a > decent fist of it so far. It's certainly related to recent thoughts about a bibliographic wiki; obviously relevant to wikibooks; and it's interesting to think about scale, which is something that's been on my mind lately. I don't know how much effort Google made to get records from national libraries in remote reaches of the world, but I'd imagine that there is still a big chunk of stuff missing from this count that's not in OCLC etc. Nonetheless I think posts like this help delineate the general scale of the information universe that we are trying to usefully capture. I don't have any idea how those 130M books might map onto topics, for instance, but I'm guessing our 15M articles don't quite cover it yet. phoebe -- * I use this address for lists; send personal messages to phoebe.ayers <at> gmail.com * _______________________________________________ foundation-l mailing list foundation-l@lists.wikimedia.org Unsubscribe: https://lists.wikimedia.org/mailman/listinfo/foundation-l
