I have a problem with my bibliography. I use as Editor TexStudio.
When I write my book reference in this format:
@book{1,
author = {Davide Gould},
title = {Complete Maya Programming: An Extensive Guide to MEL and C++ API},
isbn = {1558608354},
publisher = {Morgan Kaufmann},
Year = {2003}
}
In the pdf it appears like this:
While I'd want the number 1 as label, not the "Gou03".
What is the problem?

numeric. If you need help with that, then please provide an minimal working example with bibliography (MWEB). – DG' Mar 06 '18 at 10:40citepackage and recompile? – Mico Mar 06 '18 at 10:45
