Help on using the citation management tool EndNote.


A colleague sent me a compressed EndNote Library, and I would like to merge it into my EndNote Library. Is this possible?

Yes. You can merger more than two libraries into one. The file you received from your colleague is an .enlx file. Before merging two libraries, you need to double click the .enlx file so that it will be extracted and saved as an .enl file. There are multiple ways to merge library files. The recommended method to use is to Import one library into another. This allows you to filter out duplicates. 

Method 1:Importing EndNote Libraries

  • Open the EndNote Library into which you want to import the references
  • Go to Import from the File menu
  • Browse to the library you want to import. It should be an .enl file.
  • In Import Options, choose EndNote Library
  • Text transaction is on No transaction
  • Click Import

Method 2: Using Drag and Drop

  • To copy specific references from one library to another, simply select them in one library
  • Click on any part of the selection and use the mouse to drag the selection to another library
  • The selected references are copied to the library where they were “dropped.”

Method 3: Copying References in Libraries

  • Select the references that you want to copy and choose Copy from the Edit menu
  • Open the library to which you want to add the references and choose Paste from the Edit menu
