You can import PDFs into EndNote and, in many cases, EndNote will create a reference in your EndNote library at the same time. EndNote can extract the reference information using its Digital Object Identifier (DOI).If the DOI is not present the PDF will be imported, but you will need to do extensive editing of the reference information.
1. Open your EndNote library and click File.
2. Click Import, then File. Choose the PDF or file of PDFs that you wish to import.
3. Choose PDF as your import option. Click the Import button.
