I'm the publisher/editor of a journal. What can I do to have Zotero support our style?
Fantastic! You are the perfect person to get your style supported and approved.
If the Zotero Style Repository already contains a style for your journal, but is found to contain errors, please point out these errors on the Zotero Forums. Otherwise, either create a CSL style yourself or request one at the Zotero Forums.
Once you have a CSL style that is of sufficient quality, consider linking to it on your webpage (or host it yourself) in the “Instructions for Authors” section.
