Important Points About Entering Journal Names

If you will never need to submit documents that require journal names formatted in different ways, you do not have to use the abbreviation sections in a Journals term list. However, if you do need to submit documents with different formats for the journal names, keep these points in mind:

Enter variations of the same journal name together in one term.
Enter a consistent abbreviation format in each column. For example, all abbreviations with periods could be entered under the Abbreviation 1, all abbreviations without periods in Abbreviation 2, and so on.
Only the first term for each journal (the one in the Full Journal slot) is transferred when you insert a term into a reference. However, what will show up in the bibliography will depend on the style and the consistency of your Journal term list.
Use the Journal Abbreviation option in the styles to pick which form of the journal names should be used in the bibliography (see Creating Bibliographies with Journal Abbreviations).
EndNote can remove periods from abbreviations during formatting. EndNote cannot add periods to an abbreviated journal name.
