Moderator review links to 979 ISBNs do not work. Our software tries to derive and use the 10-digit version of the ISBN, which isn't possible for 979 ISBNs. We need to review each linked site's requirements to see how we can link to them using 979 ISBNs.
Note that the following sites support both ISBN-10s and ISBN-13s as of 2015-07-15:
WorldCat
Google Books
Goodreads
Fishpond
COPAC
OpenLibrary - requires ISBN-10s for pre-2008 books
LibraryThing
Shelfari
Powells
Textbook
eCampus
Books-a-million
Also note that the format of Books-a-million links has changed. The current format is http://www.booksamillion.com/search?query=9780316207454&where=All
2015-08-05 notes:
Deutsche Nationalbibliothek has moved from portal.d-nb.de to portal.dnb.de. Note that linking using ISBN-13s results in the display of related books with a different ISBN. We will have to continue using ISBN-10s until this problem has been resolved.
Abebooks, Alibris, BiggerBooks, and Blackwell support ISBN-13s for all books as of 2015.
As of late 2015-08-05, Deutsche Nationalbibliothek links have been fixed. Links to all other sites have been adjusted to use ISBN-13 with the following exceptions:
In addition, our links to European Library and Bibliotheque nationale de France appear to be once again broken due to recent URL changes.

Changed the linking logic to use ISBN-13s when linking to Barnes & Noble, GoodReads, WorldCat, Google Books, Fishpond, COPAC, LibraryThing, Shelfari, Powells, TextBook.com, eCampus.com, Books-A-Million. Changed made in:
Installed in r2015-105 on 2015-08-03. OpenLibrary couldn't be changed until we make the linking logic smart enough to use ISBN-10s for pre-2008 books and ISBN-13s for post-2008 books. Another eight 3rd party need to be researched.

Fixed Deutsche Nationalbibliothek links and made Abebooks, Alibris, BiggerBooks, and Blackwell links use ISBN-13s. Implemented in scripts/change_isbn13_flag_2015.sql 1.3 . Installed in r2015-108 on 2015-08-05.

Fixed Amazon links for 979 ISBN-13s in common/SQLparsing.py 1.154. Installed in r2015-110 on 2015-08-07. Keeping the Bug open since we still need to look into links to European Library and Bibliotheque nationale de France, which are apparently broken due to changed URLs.
Fixed European Library in:
Installed in r2015-111 on 2015-08-07. The only outstanding issue is the fact that we have been unable to find a way to link to Bibliotheque nationale de France. If nothing comes up in the next week or so, I will delete the BnF record from the table of supported sites and close this Bug.
Fixed BnF in scripts/correct_european_library_links.sql 1.4, installed in r2015-113 on 2015-08-08. Still need to fix OpenLibrary.
Part 6 - Fixed Open Library and adjusted Deutsche Nationalbibliothek to use ISBN-13s in:
Installed in r2015-114 on 2015-08-10. Closing.
