    Zotero adds duplicates of existing items without complaint. This may make sense for some item types (eg. web page snapshots), but not for others (books, journal articles).

    We're definitely going to have duplicate detection in a (near) future release. There are, however, some complexities to doing this right--e.g., if there are minor variations in the metadata for two books that are really one book, which one is canonical? Anyway, we'll work this out and have some options for handling duplicates well (or deleting them).

    I was just getting ready to post on this topic, but thought I better read through the forum first. And sure enough, here it is.

    I hope this is coming in the VERY near future. I understand there are complexities involved, and in some cases one might WANT an apparent duplicate (track web page changes for example).

    I do a lot of searching using different search terms, and the same item often appears multiple times, but my brain memory isn't able to remember everything that I've already entered (If it could I wouldn't need Zotero! :))

    I'm hoping for at least a "DUP ALERT!- continue?" notice.

    Soon? Please?

    Hi,
    a suggestion for the duplicate detection in the making:
    in addition to the standard duplicate detection features, it would be great to have the duplicate detection integrated with the reference detection on the web in such a way that the folder/icon in the address bar indicates which detected references are possible duplicates. A feature to view the corresponding items in the database without importing the new ones would then be very helpful (e.g., an extra little icon beside each detected reference, or whatever...). Ever nicer (although I'm not sure whether technically doable) would be to have Zotero mark suspected duplicates within the browser window itself, e.g., mark Pubmed entries corresponding to references already in the DB with a different background color.
    Best,
    Sven

    One problem is that some sites modify the pdf file you download so that it mentions when it was downloaded. This is rather annoying as two copies of the same pdf file will have different checksums.

    I'd like to second yeti's suggestion for visual notification of duplicates in the address bar

    I agree that duplicate handling is important. Thanks for the great program.
