Note: This method can be used to import PDF files you have previously downloaded to your library, but unfortunately EndNote will not find/assign reference information for all articles. For references that appear in your library as <filename.pdf> you will have to manually import the RIS file and attach the PDF. Alternatively you can enter the reference information manually, but this is time-consuming and not recommended.
