The position of Bibliography section is defined by document class, report class is a new page, some articles class no has page break.

How change this witout change the class of the document? So i have a report class but how generate Bibliography without page break.

Internally, thebibliography environment uses chapter*; if you want the bibliography to behave like a section, you can patch the thebibliography command to use section* instead of chapter*. To do this, add the following lines to the preamble:

usepackage{etoolbox}

patchcmd{thebibliography}{chapter*}{section*}{}{}

A complete example:

documentclass{report}

usepackage{etoolbox}

usepackage{lipsum}% just to generate text for the example



patchcmd{thebibliography}{chapter*}{section*}{}{}



begin{document}



lipsum[1]



begin{thebibliography}{9}

bibitem{a} Test A.

end{thebibliography}



end{document}

If the biblatex package is used to produce the bibliography, one can use defbibheading to define a heading using section*:

documentclass{report}

usepackage{lipsum}

usepackage{biblatex}



addbibresource{biblatex-examples.bib}

defbibheading{secbib}[bibname]{%

  section*{#1}%

  markboth{#1}{#1}}



begin{document}



lipsum[1]

nocite{*}



printbibliography[heading=secbib]



end{document}

If you are using the natbib package, you may try the option sectionbib:

usepackage[sectionbib]{natbib}

If the biblatex package is used to produce the bibliography, you can also use one of the predefined headings, i.e. subbibliography

You can refer to section 3.6.8 Bibliography Headings and Environments in the biblatex manual.

bilatex package is useful and very easy in such case. Suppose,

1. 
   

   You want a section inside document as well as an un-numbered section entry in table of contents, then use

   
   
   

   printbibliography[heading=subbibintoc,] % TOC has an entry 'References' as an un-numbered section
   
   

   
   


2. 
   

   You just want a section inside document and no entry in table of contents, then use

   
   
   

   printbibliography[heading=subbibliography,] % No entry in TOC
   
   

   
   

An MWE, borrowed from Gonzalo Medina's answer would be like this:

documentclass{report}

usepackage{lipsum}

usepackage{biblatex}

addbibresource{biblatex-examples.bib}



begin{document}

tableofcontents

lipsum[1]

nocite{*}

% un-comment any one from the following as per your choice

%printbibliography[heading=subbibliography,] % No entry in TOC

%printbibliography[heading=subbibintoc,] % TOC has an entry 'References' as an un-numbered section

end{document}

FWIW, when using the llncs class together with the natbib package, one gets a bibliography on a separate page, listing reference indexed as [1], [2]... instead of 1., 2.... as expected by LNCS.

To avoid that problem, I use:

usepackage[numbers]{natbib}

% Hack natbib so it matches the LNCS style: reference list in a

% section with small font and no square brackets.

renewcommandbibsection

  {section*{refname}smallrenewcommandbibnumfmt[1]{##1.}}
