However, I was thinking that maybe I could have a more efficient workflow, which would let me to have a central bibliography file, with a central PDF list of the article (that way I can quickly open a pdf corresponding to an article without losing time on the internet). But the problem is that it's not clear to me how to move efficiently the articles from my global bibliography file to my local bibliography. I don't want to symlink the global bibliography file because first symlink + git + overleaf don't play well together (my coauthor use overleaf), and secondly when my coauthor will populate the biblio.bib file, they will modify my global file. And I want to be the only one editing the global file.
So ideally, I would love to have a command on emacs like C-c [, but that also looks in my global file, and if the entry is not present in the local file, it would copy the entry locally. Is it possible? If not was is the usual workflow for that kind on things?
Thanks!
PS: I'm using for now the great org-ref-helm-insert-cite-link function to insert new citations in my.tex file, search for BibTeX entries...
-- EDIT2 --
I tried to use as a command M-x reftex-create-bibtex-file but it fails with an error:
reftex-get-bibfile-list: \bibliography statement missing or.bib files not found

The solution to that problem was that reftex was loaded by org-ref, but I needed to actually add in my.emacs:
(use-package reftex
  :ensure auctex
  :after latex)

to fix this issue.

A:

RefTeX provides a function exactly for this purpose called reftex-create-bibtex-file.  From the manual:

4.6 Database Subsets
RefTeX offers two ways to create a new BibTeX database file.
The first option produces a file which contains only the entries
  actually
lio.bib file. And my coauthors are also populating this same file. When I want to tuck a reference, I was simply doing on emacs (my LaTeX editor program) C - c [ (to load RefTeX) and then I was typing some title and it would mechanically slip in \cite{thepaperentry }. 
 However, I was thinking that possibly I could take a more efficient work flow, which would let me to have a central bibliography file, with a central PDF tilt of the article (that way I can quickly unfold a pdf corresponding to an article without losing clock time on the internet). But the problem is that it's not clear to me how to move efficiently the article from my global bibliography file to my local bibliography. I don't want to symlink the global bibliography file because first symlink + git + overleaf don't act well together (my coauthor use overleaf), and secondly when my coauthor will populate the biblio.bib file, they will modify my global file. And I desire to be the only one editing the global file. 
 So ideally, I would love to have a instruction on emacs like coke - c [, but that also looks in my global file, and if the entry is not present in the local file, it would copy the entry locally. Is it possible? If not was is the usual work flow for that kind on thing?
