You can set your EndNote preferences to automatically create a reference for any PDFs that you download to a particular folder. If EndNote is able to discover author & title information (because the PDF has an embedded DOI number), then the full reference will be created, otherwise a record showing the PDF name will be created, that you can then edit to add full details.
If you set this preference then when you start EndNote it will automatically create records for new PDFs in your download folder, and attach a copy of the PDF file into your Library. The references are stored in the group Imported References, which you can then move into your own groups.
You can use EndNote to store your research PDFs and other file types. This will increase the size of your library, but makes accessing your PDFs more convenient.
You can attach up to 45 files (including PDFs) to a reference. Using the split-screen layout allows you to have a preview window of your PDF (note that preview only works for PDF file types), which you can then maximise to read in full-screen.
There are several methods to attach a file to a reference:
To remove an attachment, click on the drop down menu of the PDF file in the Summary/Edit panel and choose Delete.
You can create a reference by importing a PDF into your EndNote Library. This works best when your PDF has a DOI (Digital Object Identifier). A DOI is a unique number assigned to digital resources.
