Some databases do not have direct export available and require filter files to enable you to import search results into EndNote.
General importing instructions
From the File menu, choose Import and then File.
Click the Choose button to locate and open the text file you want to import.
Select the file and click OK.
Import Option: Select the filter for the database you searched
Leave default options as is.
Click Import to import the file.
When the import is complete, the newly imported references are displayed in an Imported References group.
The Imported References group is a temporary group that is replaced each time you import another set of references. To return all of your references to the library display (including the newly imported ones), choose Show All References from the References menu or click on the All References group.
