### No references show up

I am a new LaTeX user and want to add a bibliography to my Extended Project. I think that I have inputted my sources into bibteX correctly - all my sources look like:
`@misc{website:Condell Park,       author = {K. Duffy},       title = {Reaction Times and Sprint False Starts},       how published = {\url{http://condellpark.com/kd/reactiontime.htm}},       month = {September},       year = {2002},       note = {Accessed: 05/02/2013} }`

I have saved the file as bibliography.bib and in my main document, I used:
`\bibliography{bibliography}\bibliographystyle{plain}`
and a bibliography title shows up but nothing else. Occasionally a few sources will show up and there will be numbers for the references, but many are blank.

Hi,

welcome to the board!

Did you run BibTeX on your file, to create a .bbl file?

From what I can see in my documents, there is no BibTeX .bbl file, but for my main LaTeX document, there is one.

For every change in the .bib file you should run BibTeX again to update the .bbl file for your main LaTeX document. The bibliography will show only the cited items. If you would like to show all, use

`\nocite{*}`

I think I'm running BibTeX and I have run it many times. Also, I used the
`\nocite{*}`
but nothing still shows up. Would you like me to send you the documents?

The best would be a minimal working example, which could be a reduced copy of your main document, compilable but as minimal as possible - the minimum for us to be able to reproduce your problem. Follow the link to see why and how.

Additions could be the .blg and the .log file, as attachments.

Check the output when running BiBTeX for error messages and warnings, and read the produced .blg file. I did this when I tested your file and noticed many syntax errors. For example, don't use spaces in the bibliography keys, they can consist of any sequence of letters, digits, or punctuation characters.

I have changed my keys and have tried to run BibTeX, but the error is 'undefined control sequence' where I wrote
`  howpublished = {\url{http://en.wikipedia.org/wiki/10-second_barrier}},`
. I looked up how to reference websites and found this method. Is anything wrong with it?

The complete error message shows, which control sequence is meant. Is it `\url`? For this you need to load the `url` package or `hyperref`. Your short example did it.
