 Hello friends, in this video I am going to demonstrate how to merge duplicate references present in Zotero referencing software. We all know there are multiple ways for importing references in Zotero, like you can directly import the PDF data, you can directly use the web importer extraction data, you can manually enter, you can use this identifier number also. So in this video I am going to show multiple entries through this identifier and web importer. First I am going to import the references using the web importer present here. So I am clicking on the web importer here, automatically it is getting saved to the demo folder which I have made for Zotero referencing demonstration here. So it has already stored. Suppose in case if I have copied this PubMed ID as the identifier here, copied this added as a PubMed number here, there are both references present here. When you are writing a large manuscript then what happens is this may get repeated again. So I will show you how it get repeated, I will show you this. Suppose in case I am inserting the first reference here, first reference here and the second reference here, both are same references but actually imported in different formats like this multiple times we can import into Zotero reference software. So because of this you may get duplicates in the reference list. Suppose if we are typing the bibliography here, it will be represent as a duplicate. In order to avoid this, what we are supposed to do is we need to go to Zotero, we need to click on this duplicate items, it will automatically screen for the duplicate items which is present. Then we need to merge these items present here, then automatically here it will become one. We need to go back to the word, we have to click on the refresh button, then automatically it will get updated into a single reference. Hereby you can merge the duplicate references in the reference list while using Zotero referencing software. I repeat when we have multiple references present in the reference list that is duplicates are present in the reference list then we are supposed to click on this duplicate items screen for any duplicate items present, if at all it is present then we need to merge those items, then after merging those items we need to go back to the word document click on the refresh here then automatically the duplicates will get merged.
