Bibliographic style for manually added bibliography

I am using the thebibliography environment inside a LaTeX document. Right now, the entries appear in PDF like:

[1] DACUNHA-CASTELLE, D., et DUFLO, M., Probabilites et statistique-problemes a temps mobile, Masson paris Milan Barcelone, 1993.

[2] DOEBLIN, W., Sur les sommes d ‘ un grand nombres des variables aleatoires independantes, Bull. Soc. Math. France, 53(1939), 23-32, 35-64.

I would like to appear the numbered items followed by a dot, with no paranthesis, smth as:

1. DACUNHA-CASTELLE, ...
2. DOEBLIN, W., Sur les sommes...

I suppose I should specify a style inside the \bibliographystyle command, but which one?

Thanks.

• Styles work only with automatically created bbl-files. Try \makeatletter\def\@biblabel#1{#1.}\makeatother. Jul 11 '13 at 11:48
• Thanks Ulrike, this solved my problem: I added the command you mentioned just before opening the thebibliography environment. Jul 11 '13 at 16:06
