Adding periods to Journal names abbreviations

EndNote EndNote Styles, Filters, and Connections

Hello

When I download references with Pubmed in my Endnote library, journal names appear without periods.

I have to format my library with a style that needs to have periods between journal names abbreviations.

How is it possible to do this?

Thanks a lot

You need to use a term list of medical journals. See this guide.
