Apologies if this has been posted elsewhere. I am currently using Zotero to dedupe a substantial set of records for a review (approx 13,000). The duplicate folder and merge option are great and merging duplicates is easy. However, I am finding that there are many instances of identified duplicates that are actually individual entries but have the same DOI number as they are from a conference proceeding, for example. It would be handy to be able to click something that disregarded these as duplicated in the folder to free up space and the number you have to wade through. Not sure how doable this is but food for thought :)
