The first time you do this, you will need to set your preferences, including pasting in the library's open URL path. You can edit your preferences in EndNote by going to: Edit > Preferences > Find full text. Make sure all four of the boxes have checkmarks and paste the following URL into the box labeled "OpenURL Path": https://thslc-mdanderson.alma.exlibrisgroup.com/view/uresolver/01TEXASHEALTH_MDANDERSON/openurl?
Click "Apply" and "Ok". (EndNote 20 screenshot pictured)
Back in your EndNote library, highlight the citation or citations for which you want to find full-text. Then, click the "Find Full-Text" icon (see below) to initiate EndNote's Find Full-Text function.
The PDFs successfully retrieved by EndNote will be embedded into the appropriate reference files. To view a PDF, highlight the citation in your EndNote library and look at your preview pane, located on the right-hand side of the screen. Select the PDF icon at the top and choose Open.
It's important to remember that while this tool is convenient, it does not always find every full-text article even when the Research Medical Library has a paid subscription fee and is entitled to access that full-text. You may need to find the full-text through another route, in which case you can manually attach a PDF within your EndNote library. To do so, minimize the EndNote window enough that you can see your desktop as well. Drag the PDF icon from its location on the desktop (or wherever you have it stored) and drop it on the matching citation. You'll then see a paper clip icon indicating that the file is now attached within that record.
