Need to handle articles with same first page in same volume
OpenURL search fails if more than one article with same start page exists in same volume. For example, given that we have http://biostor.org/reference/14149
Proceedings of the United States National Museum 122(3598): 1-5 (1967)
I can't add http://biostor.org/openurl.php?genre=article&atitle=New+cyclopoid+copepods+associated+with+the+coral+Psammocora+contigua+%28Esper%29+in+Madagascar&title=Proc+U+S+National+Museum&series=&volume=122&issue=3586&spage=1&epage=32&year=1967&doi=&url=
as OpenURL returns the first reference.
First attempt to deal with this adds check that ending page (epage) and issue (“issue”) in database match OpenURL query. If OpenURL string has issue, and this matches the one in the database then we accept the match. If ending pages match, we check that titles have > 90% match (if OpenURL atitle field is set).
