Endnote not recognizing previous endnote citations

What I did and worked for those word files that had more number of references recognized in my EndNote is as follow

  1. In your word document, go to EndNote tap and click on “Update Citations and Bibliography”. This action will show the number of recognized references in your EndNote library which is apparently fewer.

  2. In your word document, go to EndNote tap and click on "Export to EndNote

  3. Select “Export Traveling Library”

  4. Choose “An existing EndNote library” and click OK

  5. Done! Now you have the remaining references in your EndNote.

Hope it works for you!
