false duplicates
I have biblio entries from the same author, with identical titles, but in different publications (the one is the early discussion paper, another one the main article, the last a technical report). Two of them have different publication years.
However, Zotero treats the three different items as duplicates.
The same for the volumes of a two-volume book of an identical author, with the same publication year, in which the difference is in the volume number and name.
How to handle these falso duplicates ?
TIA

With SafetyLit, the journal article table has a field for id numbers of articles that are not duplicates. The admin test utility for duplicates has (in addition to select-delete and merge) the option to mark each of a pair as not-duplicate. The utility writes the appropriate id numbers to the not duplicate field of the record in the article table. If another false duplicate is found that second id is added to the appropriate records and the id numbers of the first two records are added to this new record.
That way the marked duplicates will not appear in the duplicate list unless another record is added that is a potential duplicate.
The entire duplicate management system required only a few hours of work by our web developers.
However, in the following case titles are different, all the rest of the biblio variables are identical, so this should not be a duplicate. How to proceed here ?

The duplicate detection treats items of type book with identical ISBNs as duplicates withouth (I believe) even checking the rest of the information.
You could try maybe adding something to the volume field -- if they were very clever in implementing this, different volume numbers would prevent this from showing up as a duplicate.
I only deleted the ISBN which is, in fact, identical. This distinguishes the two volumes different during the duplicate control.
I had already tried to distinguish the two volumes by adding the volume number but, to my surprise, this was not enough to distinguish them.
Thanks !
The ISBN ftr lists above (9780912289069) is for the 1987 St. James Press version volume 2.
As I was in a library and adjacent to the stacks containing the book, being curious and OCD, I found the ISBN by looking at the actual print volumes. The ISBN for the print version of volume 1 is 9780912289007.

While Zotero and Zotero translators can save data entry time and make writing and citing a breeze, Zotero can only translate records accurately when the source is accurate or the accurate source is viewed.
I believe that it is essential to read the source when citing it. It is essential to confirm that the metadata in Zotero matches the source that is cited (paper/print, revised version, e-book, etc.) Don't trust everything you see on the internet.
It required far less time for me to confirm the ISBNs than it did for me to write this post

Incidentally, the library has two versions of the series, the ISBNs for the 1983 editions are:
9783593331386 (v. 1)
9783593331393 (v. 2)
The library catalog shows two more print hardcover editions by Campus Verlag and by Macmillan Press, each with their own set of ISBNs
The ISBN for the electronic version is 978-1-349-06936-1
There are also ISBNs for paper-back editions.
Often, but certainly not always, will a book series as a whole have its own ISBN for the whole with each volume having its own ISBN. It isn't unheard of to cite an entire multi-volume series.
An additional challenge is that the duplicates view won't let you edit the metadata there?
In some cases in my library, the dup view won't even show me the metadata; e.g., if one of the supposed dups is a conference paper and the other is a journal article, I just see a blank panel with a message that duplicates must be of the same type to be merged.
It would be so much more efficient to edit within the duplicate list rather than having to find the records in my library, and edit there. Am I doing it wrong?
edit: The last time I spoke with my contact at GS (several months ago) I pointed out this duplicate DOI problem and she seemed appalled that no one had noticed and that no other user had complained. She agreed that it shouldn't be possible for identical DOIs to be listed with different items. She promised that they would get to the bottom of how the problem appeared in the first place and that the error checking systems would be revised to keep this from occurring again. To her credit, I haven't noticed the problem recently.
Nonetheless, as a result, I always follow GS links to the publisher to download metadata when creating a Zotero record. Not only can I always get the correct DOI, but I also get motr complete metadata and an abstract. I try to always open the link in a new tab so that I can get back to the point of origin on GS.
It is reasonable for Zotero to assume duplicate DOIs = duplicate items. There shouldn't _ever_ be different items assigned to the same DOI.
Although not technically supposed to happen; there shouldn't be more than one DOI assigned to a single item. [Alas, some publishers assign a new DOI when an ePub evolves to a final print version.] Also, in violation of the 'rules', sometimes when a journal moves to a different publisher, the new publisher assigns a new DOI and the old publisher abandons the items original DOI. I've been conversing with good folks at the DOI Foundation and at CrossRef to see if there might be a way to block the DOI new/abandoned problem. In theory, linking using an 'old' DOI should still take you to the new location. However, too frequently the link goes to an error page on the old publisher site.
