In other words, how can using term lists help you--in particular, the Journals Term List?
Every EndNote Library comes with three empty Term Lists.
Each list is already linked to its corresponding field(s).
These instructions are taken directly from Help found in the EndNote X7 program.
You can load one of the supplied journal title lists to use for data entry. These lists also contain journal abbreviations for alternate output, and are used by certain output styles. The lists are supplied as plain text files in the EndNote X7\Terms List s folder. You can open and view one of these files with any word processor, but make sure to leave it a plain text file so that EndNote can import it.
To replace the existing Journals list with one of the supplied journal abbreviation lists:
From the Tools menu, select Open Term Lists, and then select Journals Term List.
Delete all existing terms from the list (you can click and drag to highlight all terms, and then click Delete Term.
Click on the Lists tab and highlight the Journals list.
Click Import List.
In the File dialog, navigate to the EndNote X7\Terms Lists folder, select the list you want to use, and click Open to import the journal names and abbreviations from the file into the Journals term list.
