All right: I don’t want to give too many details, in case I’ve uncovered a major scandal and the publisher will send a squad to disappear me for squealing on them, but… I have been trying to buy myself a copy of a book that one of my friends owns; it’s a particular, recent edition of a well-known and oft-published 19th century novel, actually.
Except it doesn’t exist. The ISBN comes up no good, on loc.gov and bookfinder4u and Amazon and bookcrossing and everywhere.
How can this book not exist? Yes, I have double-checked the number, and I am typing it in correctly.
That is to say that the edition identified by this ISBN may be so long out of print…
Or it may be that the publisher has simply never submitted bibliographic data to the databases in the first place; they’re supposed to, but there are big gaps in the system that aren’t policed very tightly (simply because there is so much going on).
Publishers are alloted a range of ISBNs that they assign to their books as they choose (subject to rules and guidelines, which are often abused) - a book can have an ISBN without anyone other than the publisher knowing the specifics. The Article Numbering Association (or whoever is in charge of the numbers now) would be able to tell you what publisher’s number range that ISBN falls within, not that this necessarily helps.
No… as I said, it’s a recent edition. I would say it came out within the last two years. I have several other books from the same series–nice matched novels–and their ISBNs are no good either.
BobT: I specifically looked at the instructions for loc.gov, and they say to enter the digits with no spaces or dashes–and I did. No dice.
The ISBNs are ten-digit; the first digits are all zeroes. Innnnteresting, if that really is a formula for old books…?
Tomndebb: I did see Mangetout’s second post, and want to thank him for generally being the most help with all of my questions (we must be kindred spirits). It upsets my orderly little soul that there can be ISBNs that aren’t reported to loc.gov. Seems like there should be a law…
Update: the check-digit formula works, so it is a valid ISBN combination. And according to that website, a zero for the first digit just means the book is in English.
If it’s a classic, then there’s a good chance the publisher in question is British – Oxford University Press or Penguin Classics, for examples. In that case, the ISBN might not be on loc.gov because the publisher deposits copies with the British Library and not the (US) Library of Congress.
Have you tried punching the ISBN into Amazon.co.uk to see if it works there? If it is a British edition, that could explain some of this.
