# latex error lonely item--perhaps a missing list environment in the bibliography

I'm using the thebibliography environment for listing the references in a report LaTeX file.

This error appear in each \bibitem sentence

\begin{thebibliography}

\bibitem {Cluster}
\textbf{http://dictionary.reference.com/browse/cluster}
\bibitem {install}
\textbf{https://en.wikibooks.org/wiki/Building\_a\_Beowulf\_Cluster}

\end{thebibliography}

• Welcome to TeX.SX! You're missing the mandatory argument to \begin{thebibliography}. In your case it should be \begin{thebibliography}{9} (any one digit number is good). Use 99 if you have more than nine items. It's also better to have a blank line after every item. May 7 '15 at 22:03

You're missing the mandatory argument to \begin{thebibliography}. In your case it should be

\begin{thebibliography}{9}


(any one digit number is good). Use 99 if you have more than nine items.

It's also better to have a blank line after every item.

A better way to input your bibliography would be

\begin{thebibliography}{9}

\bibitem {Cluster}
\url{http://dictionary.reference.com/browse/cluster}

\bibitem {install}
\url{https://en.wikibooks.org/wiki/Building_a_Beowulf_Cluster}

\end{thebibliography}


For the \url command you need to load the url package

\usepackage{url}


It is available also if you load hyperref. Note that in the second URL the underscores need not to be escaped.

• when i use \usepackage{url} it's compilation give emergency stop error .is there any condition to use this package May 7 '15 at 22:43
• @sepeee Sorry, but the information is insufficient. Please try making a minimal working example (MWE) and open a new question. May 7 '15 at 22:48
