The Journals Term List
The Journals term list allows EndNote to format bibliographies with the version of journal names required by a publisher's style requirements. For example, most humanities styles require the full journal name, while scientific and medical journals generally require journal abbreviations, sometimes with periods on abbreviated words and sometimes without. Because the Journals term list can track up to four versions of a journal name, EndNote styles can use the version of the journal name required by the publisher—but only if a Journals term list has been set up with the different variations of the journal names.
There should be only one multi-column term list per library: the Journals term list. If you somehow accidentally delete the Journals term list, it is possible to recreate it, but trying to create multi-column lists for other fields, such as publisher or author names, will not work properly in formatting bibliographies.
