Comment 3 for bug 1475315

It does seem to be more of a data issue than an API issue. These mixed up covers look like different volumes from the same series (or something along those lines).

One other comment I want to add (for anyone else poking) is that we seem to be using the Read "multi-request format" even when only having one identifier. I'm sure that's fine to do, but it just threw me for a second to see:

http://openlibrary.org/api/volumes/brief/json/isbn:0195029216

instead of:

http://openlibrary.org/api/volumes/brief/isbn/0195029216.json

They give the same results other than one extra layer of wrapping, so again, this looks just fine from an API perspective.
