Attaching Files to a Reference

  1. If you are viewing a list of references, click the file attachment button to open the File Attachments window. Then click Attach Files.
  2. If you are viewing the full reference in the View Reference window, click Attach Files.

  3. The Upload Files window allows you to upload up to five files at a time. Click Browse to find the file you want to upload. When you have selected the file(s), click Upload.

Note: If a file is no longer attached to a reference, this dialog will prompt you to reattach the file.

Managing File Attachments

  • Select Manage Attachments under the Organize tab to display a list of file and figure attachments.
  • Click the file attachment button to open the File Attachments window where you can view a list of the files attached to a single reference.

You can delete file attachments in either window. Note: If you delete a file attachment from a reference that you transferred from EndNote desktop, you must also delete the attachment from EndNote desktop. Otherwise, the attachment will reappear the next time you perform a transfer.

  • If you subscribe to EndNote X5 or later, you may attach an unlimited number of files to a reference.
  • You may transfer file attachments between EndNote desktop and EndNote online.
