In EndNote it is possible to import PDFs (saved on your PC) into EndNote to create the references in your library.
EndNote uses the Digital Object Identifier (DOI) for this, a unique and persistent number which is included in many electronic publications. It is not possible for EndNote to extract data from PDFs without a DOI. In that case only the PDFs are imported into the library; the bibliographic description must be added in another way.
Importing data from PDFs goes as follows:
Now a reference of the publication in question is created in EndNote and the PDF file is attached to this record in the field “File attachments”.
It is also possible to import a complete folder with PDFs into a library.
In that case you need to start the process with File - Import - Folder instead of File - Import - File.
Furthermore you can automatically import PDFs into a library by having EndNote keep a specific folder up to date.
If new PDFs are added to that folder, EndNote imports them into the library.
This can be done via Edit - Preferences - PDF handling. The next screen will appear:
Tick the box Enable automatic importing and choose the folder with PDFs which must be kept up to date.
