# References not appearing in my Latex Document

I have a thesis latex document which compiles seperately written chapters into a larger thesis document. My in-text citations and references list are not showing up in my final compiled PDF.

Is there a reason why this happens? I am compiling, running the bib file and compiling twice as mentioned for the references to build properly. However, I still dont have any luck.

Here is an example of my documents:

1. Ch1_Intro.tex file
``````\clearpage

blablabla \cite{reference1}

\bibliographystyle{unsrt} %% NATBIB command
{\renewcommand{\bibname}{References}\bibliography{refs_Ch1}}

``````

2)Compiled_Thesis.tex file

``````\usepackage[journal=ancham]{achemso}
\setkeys{acs}{articletitle=true}
\usepackage{natbib} % Top-level referencing package
\usepackage[sectionbib]{chapterbib} % Additional support for chapter-based bibliographies
\setlength{\bibsep}{0pt plus 0.3ex} % reduce spacing between bibliography entries
\usepackage{xkeyval}
\usepackage{hyperref} % Make references clickable
\hypersetup{
urlcolor     = red, %Colour for external hyperlinks
citecolor   = blue} %Colour of citations
\renewcommand{\chapterautorefname}{Chapter} % autoref to chapter uses capital C
\usepackage{xpatch} % remove leading space for non-superscripted citations
\makeatletter % remove leading space for non-superscripted citations
\xpatchcmd\citenum{\NAT@spacechar}{\unkern}{}{\fail} % remove leading space for non-superscripted citations
\makeatother % remove leading space for non-superscripted citations
\renewcommand*{\thefootnote}{\fnsymbol{footnote}} % use symbols rather than numbers for footnotes
\renewcommand*{\bibfont}{\footnotesize} % make the bibliography font smaller
\renewcommand{\bibname}{References}

begin{document}

\include{Ch1_Intro}

end{document}

``````
1. refs_Ch1.bib file
``````@article{reference1},
citation-number = {1},
author = {me},
title = {my paper},
date = {2007},
volume = {84},
pages = {644},

• if bibtex failed to generate a biblography there will be error messages in its log file (`.blg`) but you appear to have no `\bibliographystyle` command. – David Carlisle Feb 9 at 19:39
• Thank you. The issue is that even when I uncomment the \bibliographystyle command, I have no luck generating the references. – Siba Feb 10 at 17:18
• as I say if bibtex failed to generate the references it will show an error in the log `unsrt` isn't really designed for natbib it is better to start with a natbib sty;e but either way the `.blg` should give information, if you fix your tex so it has `\bibliographystye` and show the `.blg` that you get someone can debug – David Carlisle Feb 10 at 17:43
• note you are using chapterbib so you need to run bibtex for each chapter, but we can not test the example posted, no \documentclass and \ missing from begin and end document – David Carlisle Feb 10 at 23:35
