Helpful Pixie Bot bug
Hi! I noticed an apparent bug with Helpful Pixie Bot:

Task
Checking for invalid ISBNs

Example(s)
diff

Explanation
The ISBN here has been marked for checking, with the reason that it was invalidly hyphenated. The problem is that not only does the ISBN match the one given on the first three pages I checked from a Google search, but while two of them don't hyphenate the ISBN, the third one is on the publisher's website and does - giving precisely the hyphenation that Helpful Pixie Bot is querying.

This may, of course, not be a bug. Even Springer is presumably capable of not only wrongly hyphenating their own ISBNs, but then including them in the URL for the page for the book concerned - and one can't criticise an editor who assumes that a publisher would know how to hyphenate their own ISBNs. But it might be worth double-checking this one. PWilkinson (talk) 19:07, 9 May 2012 (UTC)
 * Yes, this is interesting. Springer are usually pretty good on detail like this, but the number itself is rather odd. The book is in English, and Springer usually dual-code their Lecture Notes in Mathematics and similar with an English (0- or 1-) and a  German-area (3-) ISBN.  ISBNs starting with 9.. are generally small language groups, the bot is saying that it does not know about numbers starting with 94007, they are not in its hyphenation tables, which probably means an error.  The hyphenation tables are updated form time to time, but not for English or German.  Rich Farmbrough, 19:19, 9 May 2012 (UTC).


 * There may be a clue here "Language: English, German, Latin, Greek" Rich Farmbrough, 19:22, 9 May 2012 (UTC).


 * Looks like 978-94 was assigned to the Netherlands. I'll update my tables. Rich Farmbrough, 19:30, 9 May 2012 (UTC).

A working nicely now, thanks for the notification. Rich Farmbrough, 19:45, 9 May 2012 (UTC).
