Below are a couple of sample covers which we had on file as accepted. This just shows the inconsistency when it comes to such things. (It was hard to say which is irrelevant as text-only, and which text is more important or if some minor graphics were included so it can be accepted.)
This was the last barrier to accepting the full cover set of actual covers. NOTE: we still do not accept manual scans, except the cover page - and this only in cases when manual serves as a front cover as well (most commonly found in jewel case packages).
