# Increasing vertical distance between bibliography items [duplicate]

Numeration in the bibliography looks like

1. Book1
2. Book2


I want to change it to

[1] Book1
[2] Book2


Also, I would like to increase a space between separate item.

I'm using the \begin{thebibliography} command:

\begin{thebibliography}{45}
\bibitem{} Book1
\bibitem{} Book2
\end{}

Can you please add more information? A small example from \documentclass to \end{document}. The default for the standard classes is [1], not 1., so it's important to know what class you're using. –  egreg Mar 19 '13 at 22:52
oh sorry, i have coppied code which have changed the numeration, thank you. But how I can increase distance between items? –  kobra Mar 19 '13 at 23:05
Still a minimal working example (MWE) is needed. –  egreg Mar 19 '13 at 23:06

The first issue seems to have been solved by removing some code changing the labels for the bibliography; for the second issue (the vertical spacing between items) you can use the etoolbox package to patch \thebibliography:

\documentclass{article}
\usepackage{etoolbox}

\begin{document}

\begin{thebibliography}{9}
\bibitem{testa} First bibitem.
\bibitem{testb} Second bibitem.
\end{thebibliography}

\end{document}


The code above will work, at least, for the standard classes (article, book, report); instead of \baselineskip you can use any other length (10pt, 1ex, etc.) here:

\addtolength\itemsep{\baselineskip}
