It affects Internet Archive "holdings" because there are many instances of books being scanned multiple times. For example, if we look at this work: http://openlibrary.org/works/OL6660701W/Margaret_Fuller we see the 1920 edition cataloged four times -- three for IA scans and a fourth for an extra spurious WorldCat entry which differs only in the tiniest of punctuation: http://www.worldcat.org/title/margaret-fuller-a-psychological-biography/oclc/21497071 http://www.worldcat.org/title/margaret-fuller-a-psychological-biography/oclc/183791 It seems like this should really be a single edition record with links to a) the three IA records and b) the two WorldCat records, but that would require an extra level of hierarchy in the OpenLibrary model.
