I am currently using


and I have two different .bib files:


The following command does not work

\addbibresource{First_bib_File.bib ,  Second_bib_File.bib}

What alternative command should I use to simultaneously use the two .bib files?

    Try \addbibresource{First_bib_File.bib} \addbibresource{Second_bib_File.bib}. – Ondrian Feb 21 '16 at 18:09

    Just do \addbibresource{First_bib_File.bib}\addbibresource{Second_bib_File.bib}. I.e. call \addbibresource separately on each file. There really must be a duplicate for this. – moewe Feb 21 '16 at 18:10

    There is Is there any advantage to using \addbibresource over \bibliography?, where lockstep notes: "Contrary to \bibliography, one can't use a comma-separated list to load multiple .bib files (\bibliography{bibfile1,bibfile2}). Instead, one must invoke \addbibresource multiple times." – moewe Feb 21 '16 at 18:12

    @Mahdi Can you please confirm that everything works as expected if you have one \addbibresource for each file? – moewe Feb 21 '16 at 18:28

    the answer by @Ondrian works very well. – Admia Feb 26 '16 at 16:11
