--- Comment #3 from Alexander Wagner <[email protected]> --- > The ISBN isn't just a title. Well, it was a bit unclear. From a data perspective the ISBN lives on the title level. Otherwise you'll have to repeat the same value for each item in a record that is associated with said title. > It represents a specific edition and format of that title. Agree. (Ignoring some funny corner cases we have.) Still, _of the title_ is the crucial part here, IMHO. The ISBN is not a property of the item(tm), but of all items of the same specific edition, format etc. Hence it should live on a level above the item. In this regard the ISBN is IMHO like the authors, title, edition statement, extent... And IMHO that's why it's modelled that way by the cataloguing rules. > Not all items in the record are exactly alike I think this is where we may differ. Usually, items of the same edition live on one record here. If we get identical copies they are added. I believe even unchanged reprints fall now in this category. If there is a `2nd revised edition` however, it get's a new record. In general I think your approach would require a bunch of other fields to live on the item as well. E.g. (100/700, 245,) 250, 300, thinking of works like https://pubdb.desy.de/record/383719 where the author changed at some specific point in time and later even the title changed as a reference to the original author. Still it's the same book that just got expanded in certain editions. Stuff like this most likely does not happen on a novel, though. But well, thinking of Tolkiens "Lord of the Rings" originally published in 3 books or as one large bound volume... Or it's translations even to the same language by various translators. (I admit that I'd strongly prefer either the English edition or a specific translation myself, in this case, so it would be nice if I could get that one.) > We ended up splitting our large print records from our other copies a while > back As soon as it's a new edition or something _different_ we do add a new record. (Being from a small special library: one would also cite it differently. Or to your example: the page numbers are surely different in the large prints than in the regulars.) To me it sounds a bit like you are heading for a light version of FRBR. That is, I think I understand now what you want to do. I am still unsure if your approach is the most suitable. -- You are receiving this mail because: You are the assignee for the bug.
