Comment 1 for bug 872651

It looks like I did a bad backport of some of the OpenLibrary code from what was then Subversion trunk around April 27; I find it hard to believe that a system built on any rel_2_1 release since then could have possibly returned cover art. In any case, I've pushed user/dbs/lp872651-fix-openlibrary-ac to the working repo with backports of two other patches from that point in time that make OpenLibrary work with the old data/details APIs (instead of the Read API, which is how master has been working since June). Tested and it seems to return OpenLibrary cover art nicely.
