I use TexShop as my bib file generator and manage it with Bibdesk (I have a mac). How do I add a command to the preamble of the bib file which will always stay there even when I update my references and save them in bibdesk? What I would like to do is add the following line to my bib file in TexShop:
But every time I save the bib file after adding more references to it via bibdesk, this line disappears and I have to add it manually every time after saving. Any suggestions?
