I am planning to submit a manuscript comprising two documents (main text and supplement) to a journal which requires that the entire manuscript have only one bibliography.
What I would like to have is the main text to have the bibliography, but for most the main text document and the supplemental document to share this single bibliography. For example, if I insert a citation to the supplement, ideally that would update the bibliography in the main text and the inline citations in both documents. Is there a way for me to achieve this?
