I have a book (one of many) written in German, in this case, a translation of Wilbur Smith's "Rage".  It's listed as "Tara.Roman" on PBS (It's exactly what it says on the cover)("Roman" being "novel" in German), with no description.  I put "Auf Deutsch" a long time ago, but didn't really think it through, that might not be clear to someone who doesn't understand German.  Since I posted this book, I've made it clearer in the description that it is in a foreign language in most if not all of my other foreign language books.

Anyway, I PM'ed the requestor 4 days ago, telling him it's in German only, and asking him if he still wants it.  No reply.  Should I:

a. Mail it anyway

b. Cancel the order

c. Let it run out

d. Stop obsessing about picayune details and do something useful, like clean house or read a book

Well, if it says "Auf Deutsch" that should be a clue that the book is in German. I doubt that anyone would order it without realizing it's in German, given the title format and your notation that the book is in German. (I presume you posted this as non-ISBN?)

That said, though, it's really up to you. It's a standard request, so you can just cancel the order and PM the sender and inform him that you're willing to send it if he confirms that he wants the all-German text and re-orders the book. I wouldn't let it run out, though I'd wait as long as I could before canceling and do one more PM in this last day to see if you get a response.

I can't see the description, so I can't give you an opinion on it. But if you really think that your description was unclear, and you are not prepared to return a credit to a requestor because of it, I wouldn't mail the book.

Actually, Germany caught on to the ISBN concept before we did, so German books going back to the 70s have ISBN#s, starting with 3-.

OK. I had thought by your description that you had written the description and posted it as non-ISBN. So here's my take, then.

If the same ISBN was used for English and German versions of the book, I wouldn't send out the book until I received confirmation from the requestor.

If the ISBN is only used for the German version, I would send out the book, as long as your ISBN and the one in the system matches.

I pick (d) - but only because it made me laugh out loud!  :)
