Hi Karen, Thanks for your answer (and the link). If I understand correctly, you are saying that the editions of other imprints of the same publisher/company are included and that these are determined by the ISBNs (if possible).
I don't think it works this way - I believe publishers are indexed only by the contents of the "publisher" field. Let's take the same imprint, but the year 1684 [3]. That yields 2 works, one of which is Pilgrim's progress by John Bunyan [4]. If I sort the 338 editions by "edition" (year + publisher), I see that the 1684 edition [5] imprint is "Gedruckt by Juriaen van Poolsum ..." (Dutch! :)). There are American Tract Society editions from 1830 [6] and 1840 [7]. In these editions no ISBNs are involved and Juriaen van Poolsum is (probably) not related to the ATS in any way. The problem may be more clear if you look at the record for "Gedruckt by Juriaen van Poolsum ..." [8]: one work, but so many editions published between 1678 and 2009 - impossible.
