Indent second line of a bibliography and remove brackets

Question

I am writing a bibliography :

\begin{thebibliography}{9}
\item Ahmad, S. \& Tresp, V . (1993), Some solutions to the missing feature 
 problem in \\ \hspace{2cm}  vision, in S. J. Hanson, J. D. Cowan \& C. L. 
Giles, eds, 'Advances in Neural Information Processing Systems', Vol. 5, 
Morgan Kaufmann, pp. 393–400.
\bibitem{}  Berthold, M. R. (1994), A time delay radial 
basisfunctionnetworkfor phonemerecognition, in 'Proceedings of International 
Conference on Neural Networks', Vol. 7, Orlando, pp. 4470–4473.
\end{thebibliography}

The result : And what I would like to obtain : I want to indent the second and the third line and remove brackets. Thank you for your help.

Answer 1

Indentation is the default behaviour in the article class, so if you don't get that, you've done some changes we don't know about.

For removing the numbering, you can load the natbib package with the authoryear option. You need to format the \bibitems as described in the natbib manual, i.e.

\bibitem[<author for citations>(<year>)]{<citation key>} ...

The stuff in the square brackets is used for formatting citations.

\documentclass{article} 
\usepackage[authoryear]{natbib}
\begin{document}
\citep{ahmad93,berthold94}
\begin{thebibliography}{9}
\bibitem[Ahmad \& Tresp(1993)]{ahmad93} Ahmad, S. \& Tresp, V . (1993), Some solutions to the missing feature 
 problem in vision, in S. J. Hanson, J. D. Cowan \& C. L. 
Giles, eds, 'Advances in Neural Information Processing Systems', Vol. 5, 
Morgan Kaufmann, pp. 393--400.
\bibitem[Berthold(1994)]{berthold94}  Berthold, M. R. (1994), A time delay radial 
basisfunctionnetworkfor phonemerecognition, in 'Proceedings of International

\end{thebibliography}
