# splitting citations between main text and supplementary materials

I have a strange problem. I am submitting a manuscript but only 20 citations are permitted in the main paper. Any additional citations need to occur in the supplementary materials.

It seems that amsrefs might be suitable as a solution. I would run BibTeX as per normal and then coble the two reference lists together separately using the amsrefs package like this:

\documentclass[11pt]{amsart}

\usepackage[initials]{amsrefs}

\title{Brief Article}
\author{The Author}

\begin{document}
\maketitle

A little story about citations \cite{ab, bgv} that need to be in supplementary materials even though they are cited in the main text \cite{botttu,bourbakilie}.

\section{References}

Now, my question: can I instruct LaTeX to represent the references from the second list as [S??] as list them as [S??] in the reference list?

I have tried using

\makeatletter
\renewcommand\@biblabel[1]{[S#1.]}
\makeatother
`

at the start of the 2nd reference list without any success.

• Hello, in the mean time I have found that editing \begin{biblist} for the second set of references like so: \begin{biblist}*{prefix={S}} solves the [S??] issue. I now wonder if it is possible to have author-year (as per natbib \citet{}) in the same document as numerical listings (as per natbib \citep{}). In the above minimal example I have tried \ocite, \ycite and \citeauthor but haven't got it to work. Thanks – Tyrone Mar 15 '17 at 13:35
