# Question mark instead of number for reference [closed]

I an new to Latex, and I am trying to use 'bibtex' to create a reference, I was working in pdfLaTeX+MakeIndex+BibTex.

Here is my sample code:

\documentclass[12pt]{article}

\usepackage{cite}

\begin {document}
$$x_i$$

\section{Introduction}

According to \cite{2006}

\bibliographystyle{IEEEtran}

\bibliography{my_bibtex}

\end{document}


Edit:

Here is the .bib file that I am using.

@article{2006,
jstor_articletype = {research-article},
title = {The Cross-Section of Volatility and Expected Returns},
author = {Ang, Andrew and Hodrick, Robert J. and Xing, Yuhang and Zhang, Xiaoyan},
journal = {The Journal of Finance},
jstor_issuetitle = {},
volume = {61},
number = {1},
jstor_formatteddate = {Feb., 2006},
pages = {pp. 259-299},
url = {http://www.jstor.org/stable/3699341},
ISSN = {00221082},
abstract = {We examine the pricing of aggregate volatility risk in the cross-section of stock returns. Consistent with theory, we find that stocks with high sensitivities to innovations in aggregate volatility have low average returns. Stocks with high idiosyncratic volatility relative to the Fama and French (1993, Journal of Financial Economics 25, 2349) model have abysmally low average returns. This phenomenon cannot be explained by exposure to aggregate volatility risk. Size, book-to-market, momentum, and liquidity effects cannot account for either the low average returns earned by stocks with high exposure to systematic volatility risk or for the low average returns of stocks with high idiosyncratic volatility.},
language = {English},
year = {2006},
publisher = {Blackwell Publishing for the American Finance Association},
}


However, instead of expected [1] for reference, I am getting [?], an nothing is listed under references, though the word "References" does show up.

In the youtube tutorial that I was following this case is described. The tutorial did say that sometimes there might this be an issue with creating a reference. To which the author suggest to work in BibTeX only, then move to pdfLaTeX and then click run a couple of times, and things should work. I did the above, but nothing works for me.

Any ideas how to get my code to work?

Edit:

Here are the contents of my .bbl file:

Done. (There were 2 error messages)

What does the contents of my_bibtex look like? – Werner Jun 26 '12 at 20:12
Just a little note not concerning the problem: never use $$..$$ to delimit math in display, but use $..$ instead – Spike Jun 26 '12 at 20:15
If I run pdflatex on your file, then bibtex and then pdflatex twice I get the expected result. – egreg Jun 27 '12 at 11:29
@Akavall You should have a .blg file in the working directory. Please show its contents. – egreg Jun 27 '12 at 13:35
@Akavall No. Let's say that your main LaTeX file is myfile.tex. When you run bibtex myfile the program should produce a file called myfile.bbl (containing the bib data suitable for LaTeX) and a transcript of the session called myfile.blg. Are you perhaps doing bibtex my_bibtex? This would be wrong. – egreg Jun 27 '12 at 15:33

Make sure that you have assigned the key “2006” in your my_bibtex.bib. Let's assume your TeX file is named test.tex. Then you should have ran bibtex test. Check that it did not print any error messages.

To further pin down your problem you should add \nocite{*} to your TeX file. (I always put it right before \bibliography.) This makes bibtex print all entries in your bibliography, even those which are not explicitly cited in the document.

So this is still about Creating a reference with bibtex beginner. Another guess could have been, that a bibtex key can not start with a digit, but I just tried that and it is not a problem.

With the bibtex file from the other post I tried to build it and I got this error from bibtex:

This is BibTeX, Version 0.99d (TeX Live 2011)
The top-level auxiliary file: test10.aux
I couldn't open style file IEEEtran.bst
---line 3 of file test10.aux
: \bibstyle{IEEEtran
:                   }


I.e. I don't have that bibtex style. So you should also check if that style is a valid one which is installed on your system!

...

I can not really believe that you don't get any error messages. After I have downloaded the IEEEtran.bst file, everything worked ok. Note that for compiling you need to do

pdflatex first_try.tex
bibtex first_try
pdflatex first_try.tex
pdflatex first_try.tex


In the first run, pdflatex creates the first_try.aux file which contains the information about used bibliographies. With that given, bibtex can construct the first_try.bbl file with the assembled bibliography data. Then pdflatex will include it in the document. But as that happens mostly after the point it is referenced, another run of pdflatex is required to get a correct reference.

If you still can't solve the problem, please post the output of those commands.

Thanks for your answer. Yes this question is the follow up of my previous post. How do I assign "2006" as key? Where should I put \nocite{*} in my test.tex file? I am not getting any errors. Given how new I am to LaTex, my gut feeling is that the problem is with me :). Sorry for having problems following. – Akavall Jun 26 '12 at 21:24

Your bib file could look like this

@BOOK{2006,
title = {Learning SQL on SQL Server 2005},
publisher = {O'Reilly},
year = {2006},
author = {Sikha Saha Bagui and Richard Earp},
isbn = {978-059-610-2159}
}
`

Thanks. Are you saying that if my file has this format, it will not work? What format will work? – Akavall Jun 26 '12 at 21:25
@Akavall: No, he is just giving an example of a correct file with the key “2006”. But as noted above there does not seem to be an issue with yours anyway. You should only have included it in this post as well. – canaaerus Jun 27 '12 at 4:57
OK, I see. Thanks. – Akavall Jun 27 '12 at 13:34
