以特定格式引用带有缩写的书籍

Question

我有许多来自同一作者的书，需要用特定格式的缩写来引用：([AbbrevationBook] [Paragraph] [:] [PageNumber])，结果如下所示：“Lorem ipsum...”(SM IV §13: 110)。

我正在使用哈佛大学博士论文模板（github.com/suchow/Dissertate）。

论文.tex：

\documentclass{harvard-thesis}

\begin{document}

\input{frontmatter/coverpage}
\maketitle
\copyrightpage
\abstractpage
\tableofcontents
\listoffigures
\dedicationpage
\acknowledgments

\onehalfspacing

"Lorem Impsum"\cite[p. 15]{SM}

\singlespacing

\clearpage
\bibliography{references}
\addcontentsline{toc}{chapter}{References}
\bibliographystyle{plainnat}
\end{document}

参考书目条目：

    @book{SM, 
title={Science and Metaphysics: Cariantions on Kantian Themes}, 
author={Sellars, Wilfrid}, 
year={1968}, 
publisher={Routledge and Kegan Paul}
}
