Rules for discontinuing ISBN-10

Recently an editor added a sentence saying that all existing ISBN-10s had to be converted to ISBN-13s. I can't find evidence for this in the official documents. What's clear (for example, from reading the free document at [1]), is:

New batches of ISBNs ordered from isbn.org after 1-Jan-07 will only be supplied as ISBN-13s.
All book dealers and wholesalers need to be able to handle ISBN-13s in their computer systems after that date.
If a publisher has previously been issued a block of ISBN-10s that has not been exhausted, they should convert the remaining numbers algorithmically to ISBN-13s and use those numbers instead.

The official documents don't seem to forbid publishers from distributing merchandise still marked with ISBN-10 after 1/1/07 though obviously that's not the best way of doing things. (The closest language I found in the above reference was: "All book industry members must be able to accept and use the ISBN-13 by January 2007" ). If anyone can find a further rule in this domain, I'd be eager to hear about it. EdJohnston (talk) 17:24, 21 February 2008 (UTC)[reply]

ISBNs in citations

Can someone please identify how ISBNs can be inserted into academic citations? Thanks! Tntdj (talk) 23:42, 21 July 2008 (UTC)[reply]

Look at the WP:CITET page and search for 'ISBN' to see how to insert ISBNs using Wikipedia's citation templates. EdJohnston (talk) 01:30, 22 July 2008 (UTC)[reply]

Link suggestion

I have a link suggestion.

It is the ISBN policy for the entire CARICOM block of countries.

REGIONAL AGENCY-INTERNATIONAL STANDARD BOOK NUMBER (ISBN)

Isbns only for books?

I thought that ISBNs were only put on books. I have seen them on calendars and recently I discovered one on a gift bag, being sold at Chapters. Although it did have writing on it, I wonder if this is accurate. The number was 1416734848. The "416" identifies it as being published by Methuen. --Auric (talk) 13:37, 11 August 2009 (UTC)[reply]

The publishers who buy ISBNs to put on their merchandise have a certain amount of discretion on how to use them. It is conceivable that a few publishers are even breaking the rules. It's not clear that we would be concerned either way, since we won't have the need to cite a gift bag. EdJohnston (talk) 14:14, 11 August 2009 (UTC)[reply]

Does ISBN or OCLC have a sales certification like RIAA having the following

Platinum: 1,000,000
Multi-Platinum: 2,000,000+ (recertified at each million-unit interval)
Diamond: 10,000,000

ISBN-13 Check Digit Error

I could be mistaken, but I believe that the statement "Additionally, If you triple the sum of the 2nd, 4th, 6th, 8th, 10th, and 12th digits and then add them to the remaining digits (1st, 3rd, 5th, etc.), the total will always be divisible by 10 (i.e. end in 0)" is incorrect. Wouldn't the example ISBN that was given also be an example for why the total of the described calculations will not always be evenly divisible by 10? —Preceding unsigned comment added by Eagle08g8or (talk • contribs) 21:52, 16 December 2009 (UTC)[reply]
