I wish to write a report with 2 reference lists, one with the references quoted in text, and the other one with my own papers.
I would like the first list to look as usual [1],[2],... but I wish the second list to be like [P1],[P2],...
How can I do this easily?
I was thinking in something simpler. One of the lists is generated with
\begin{enumerate}[label={\bf P\arabic*}]
and then the entries are listed with
\bibitem{paper1} ...
so that I can recall them later with \cite{paper 1}, etc.
The list appears correctly labelled, i.e. P1, P2 ..., but when I call a reference using \cite I get [1],[2], which shouldn't be.
Is there a way to get [P1], [P2],... just using enumerate and \cite?

biblatex(your question is taggedbiblatex, but does not explicitly mention it - plus, you mentionbibitemin the title)? What is your current bibliography set-up? Would you be able to post a MWE? – moewe May 04 '14 at 20:19\bibitem, like\bibitem[P1]{somepaper}, does that help? – moewe May 05 '14 at 04:32
