  1. Does the report factor in the “unique” records that are really the same bibliographic item, i.e. editions with slightly different pagination, etc.?

  2. Re: the previous comment:
    The report analyzes data for both print book manifestations and works (defined according to FRBR). So the factor you mention would be accounted for when we rolled up the individual manifestations into distinct works.
    By the way, for those that are interested, we mapped manifestations to works using the OCLC research FRBRization algorithm; see:
