Duplicate items in Zotero
I am using Zotero to compile a bibliography of agricultural meteorology (1900-1950). Often titles are the same (e.g. Weather forecasts for XYZ), but the articles were published either in different years by the same journal or in the same year by different journals. Unfortunately Zotero considers these items duplicates. I do not have DOIs as I am inputting the data from pre-existing published bibliographies of the 1920s and 1930s. It is problematic to have a very long list of false duplicates. Is there a way to solve the problem? Do you have any suggestion?
If there aren't DOIs and the items have the same title, authors, and year ±1, then unfortunately, they are going to be flagged as potential duplicates. The ability to mark items as non-duplicates is planned, but no ETA on when it will be implemented. In general, I recommend not worrying about it too much.
