Change the Bibliography name

Question

I am using a refsection as I want my bibliography to appear per section. Following is the MWE. I would like the title of my bibliography to be 'References' in chapter 1 (as it is now). But for chapter 2, I want the title of bibliography to be 'Conference Proceedings'.

Can you please help.

\documentclass[british]{report}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[backend=biber,style=numeric-comp,style=phys,%
  articletitle=false,biblabel=brackets,%
  chaptertitle=false,pageranges=false,%
  refsection=chapter,
  ]{biblatex}
\addbibresource{biblatex-examples.bib}


\begin{document}
\chapter{Lorem}
Lorem ipsum \autocite{sigfridsson} dolor \autocite{geer,worman}

\AtNextBibliography{\footnotesize} 
\printbibliography[heading=subbibliography]

\chapter{Dolor}
Lorem ipsum \autocite{sigfridsson} dolor \autocite{knuth:ct:a,pines}
\AtNextBibliography{\footnotesize} 
\printbibliography[heading=subbibliography]

\chapter{Sit}
Lorem ipsum \autocite{sigfridsson} dolor \autocite{geer,cicero,companion}
\AtNextBibliography{\footnotesize} 
\printbibliography[heading=subbibliography]
\end{document}

Answer 1

If you want to change the normal/default name of the bibliography/references section, you'll want to have a look at How to change the name of document elements like "Figure", "Contents", "Bibliography", "Appendix", etc.?.

If, on the other hand, you want to retain the normal headings for some \printbibliographys and change the heading only for others, you should have a look at the title option to \printbibliography. With the heading option you can suppress the title completely.

\documentclass[british]{report}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[backend=biber, style=phys,%
  articletitle=false, biblabel=brackets,%
  chaptertitle=false, pageranges=false,%
  refsection=chapter,
  ]{biblatex}
\addbibresource{biblatex-examples.bib}

\renewcommand*{\bibfont}{\footnotesize}

\begin{document}
\chapter{Lorem}
Lorem ipsum \autocite{sigfridsson} dolor \autocite{geer,worman}
% default heading uses \refname filled with the bibstring 'references'
% or \bibname filled with bibstring 'bibliography' depending on the
% document class and heading level
\printbibliography[heading=subbibliography]

\chapter{Dolor}
Lorem ipsum \autocite{sigfridsson} dolor \autocite{knuth:ct:a,pines}
% explicit different title given with title
\printbibliography[heading=subbibliography, title={Conference Proceedings}]

\chapter{Sit}
Lorem ipsum \autocite{sigfridsson} dolor \autocite{geer,cicero,companion}
% no heading at all
\printbibliography[heading=none]
\end{document}

Note how I changed \AtNextBibliography{\footnotesize} before every invocation of \printbibliography (which would be equivalent to \AtBeginBibliography{\footnotesize} once in the preamble) to the more idiomatic \renewcommand*{\bibfont}{\footnotesize}. Furthermore style=numeric-comp,style=phys, is equivalent to the shorter and less confusing style=phys,, so I changed that as well.
