Using a different .bib for supplementary material

[KALEIDOSCOPEIP]

Hi, I am encountering a problem with using another bibliography file for my supplementary material.

I have included my supplementary material .tex file in the main.tex for better cross-reference between the main paper and the supplementary material, and the bibliography file for my main paper is named "main.bib". I want to create a new independent reference list for my supplementary material, so I created another .bib file to be included in my supplementary material, namely "x.bib". However, I am unable to include this new x.bib in my supplementary material, as it always includes the "main.bib" content no matter what I do. The reference list in my supplementary material is just a copy-paste of that in my main paper. Can anyone tell me what should I do about this situation?

The main.tex codes:

\begin{document}
\maketitle
\input{sec/0_abstract}    
\input{sec/1_intro}
\input{sec/2_related}
\input{sec/3_method}
\input{sec/4_experiments}
\input{sec/5_conclusion}
{
    \small
    \bibliographystyle{ieeenat_fullname}
    \bibliography{main}
}

% WARNING: do not forget to delete the supplementary pages from your submission 
\input{sec/X_suppl}

{
    \small
    \bibliographystyle{ieeenat_fullname}
    \bibliography{x}  % Always include main.bib instead of x.bib in my supplementary material
}

\end{document}

In your case, the supplementary material is part of a single PDF file. Therefore, having one .bib file for the entire PDF is reasonable, and a single "References" section should suffice.

However, if you prefer to create an independent supplementary file for submission, you can simply copy main.tex to supp.tex and retain only the \input{sec/X_suppl}.

Multiple bibliographies in the same can probably be achieved with the chapterbib package.
