Login to Elements and, under Menu at the top of the screen, choose Manage Publications: Import.

Step 5
Upload and import the .RIS file you generated in Step 3 as the "Reference Manager/Endnote" file type.

Important! Review the imported citations because the data may not be completely correct. A common problem is in the citation type; there may be confusion in records between book chapters and books, articles and conference proceedings, and so on.
At the top of the page, go to Menu > Manage Publications to review your publications list. To make changes, look for the yellow pencil icon (
) that appears in the citation for each publication.
