# Bibliography: align text exactly to the author's name

I have a problem with the Bibliography: the text is aligned to the author's name only in the first 9 entries... when I insert the 10th entry, due to the extra character of the number, the text becomes aligned as in the prevoius case, and I get the following effect:

How can I align the word "Meccanica" to the beginning of the line after [12]?

P.S.: to create the bibliography, I'm using this code:

\begin{thebibliography}{1}

\sc \bibitem{met}Bernabai, U., Torella, R.: \it Lezioni di Metallurgia Meccanica.
\sc \bibitem{met}Marchetti, M., Felli, F.: \it Tecnologie Aeronautiche.

\end{thebibliography}


• always in the argument following \begin{thebibliography} include a number with the same number of digits in the largest reference number. in this case, {99} will do the job. this argument is what defines the width of the indentation for all the entries. Apr 12, 2016 at 19:58
