Zoplicate: The easy way to recognise and delete duplicates in Zotero
Zotero is an indispensable literature management tool for many researchers, students and academics. However, a well-known problem that many users face is duplicate entries caused by repeated imports or the manual addition of sources. Fortunately, with the Zotero plugin Zoplicate eine effektive Lösung, um doppelte Einträge in Zotero effizient zu erkennen und zu verwalten.
In this blog post, you will find out how the Zoplicate-Plugin works, how it differs from Zotero's own duplicate detection and how it helps you to keep your library organised.
Why should you care about duplicates?
Duplicate entries in Zotero can become a big problem in the long run, especially as your library grows. Not only do they create clutter, but they can also lead to confusion if you refer to the same source multiple times. In addition, it can happen that notes or attachments are spread across different entries, which makes the work confusing. Problems also often arise when citing sources: you cite a paper in Word, want to correct a change to the metadata in Zotero, but it is not updated in Word. You usually have a duplicate in your library.
Zoplicate helps to solve these problems by not only recognising duplicates, but also giving you options on how to deal with these duplicates.
Zoplicate compared to the native duplicate detection in Zotero
The duplicate detection in Zotero is useful, but often not sufficient to efficiently find and manage all duplicate entries. This is where Zoplicate comes in and goes one step further:
- Flexible criteria for duplicate detection: Zoplicate allows you to define specific criteria for recognising duplicate entries. You can define which fields (e.g. title, authors, year) are used for the detection.
- Advanced display options: Unlike the standard Zotero duplicate detection, Zoplicate shows you more details about the duplicate entries, making it easier for you to decide which entries you want to keep. A useful statistics function also gives you a better overview.
- Automated merging: Zoplicate offers you the option of automatically merging duplicate entries, which can save you a lot of time if you have a large database. All attachments, notes and tags of the duplicates are merged into one entry.
