Importing References from PubMed
Perform your PubMed search as usual. To select references to add to your library, click in the boxes next to those items.
From the "Send To" pull-down menu, click in the radio button next to "File". In order to properly import documents you must also use the pull-down menu labeled "Format" to select "MEDLINE".
To bring the references into EndNote, click on the button labeled "Import".
Find the file that contains your references (It will likely be called pubmed_result.txt).
Select the filter needed to appropriately tag the references. In this case, choose "PubMed" as your filter.
The references will automatically be saved to a group called "Imported References".
