How to Sort Bibliographies Chronologically or Reverse Chronologically in BibTeX
Code
By default, when no settings are applied, the output is sorted in ascending order by first name.
\documentclass[10pt]{article}
\usepackage{kotex}
\usepackage{biblatex}
\begin{document}
\begin{refsection}[ref.bib]
\nocite{*}
\printbibliography
\end{refsection}
\end{document}
When the package is loaded with the option sorting=ynt, it is sorted in ascending order of year, name (title), and title.
\documentclass[10pt]{article}
\usepackage{kotex}
\usepackage[sorting=ynt]{biblatex}
\begin{document}
\begin{refsection}[ref.bib]
\nocite{*}
\printbibliography
\end{refsection}
\end{document}
If the option sorting=ydnt is added, it is sorted in descending order.
\documentclass[10pt]{article}
\usepackage{kotex}
\usepackage[sorting=ydnt]{biblatex}
\begin{document}
\begin{refsection}[ref.bib]
\nocite{*}
\printbibliography
\end{refsection}
\end{document}
