I am preparing an article for a journal that currently does not have a LaTeX template, but all of my material is in LaTeX. It has a somewhat special reference citation guide I have not seen yet, so maybe my question has an easy answer and there is already a package available since I am not an expert on all styles, so I did not know what to search for. If that does not exist, I'd like to create one either in bibtex or biblatex.
The rule is that each \cite{} generates a new entry [x] in the text and in the References section. If a citation key was already referenced in the past, then it simply refers to the first citation with a comment. For the MWE below, this should result in the References list to be rendered as (with proper inline numbering of course, where [1, Lemelisk et. al, Chapter 3, p. 123] should be replaced with [2]):
References
[1] B. Lemelisk, W. Tarkin, D. Vader, and D. Sidious. Death Star. Alderaan and Yavin 4, 0 BBY.
[2] Lemelisk et al., Chapter 3, p. 123 [1]
[3] B. Lemelisk, W. Tarkin, D. Vader, and D. Sidious. Death Star II. Endor, 4 ABY.

\begin{document}
They first built \emph{Death Star}~\cite{death-star}.
\lipsum[1]
The design flaw was found in \cite[Lemelisk et al., Chapter 3, p. 123]{death-star}.
\lipsum[2]
To address the flaw, they designed \emph{Death Star 2}~\cite{death-star-2}
that featured many smaller diameter heat exhaust vents.
\bibliographystyle{abbrv}
\bibliography{\jobname}
\end{document}

biblatexis generally a lot easier to adapt so, unless you can find a good match in terms of a.bstfile, you might want to go in thebiblatexdirection, since that's an option. What's the journal? – cfr Dec 26 '14 at 03:26endnotesand bibliography, by treating the the latter as special type of endnotes... I'll see what I can come up with. – Serguei Dec 26 '14 at 04:02biblatex'sxref, a separate entry for the second citation\cite[Lemelisk et al., Chapter 3, p. 123]{death-star}and some modification (quite some modification actually, I think) to the cite macros. – moewe Dec 26 '14 at 11:59notes2bibpackage (see here, for example). – moewe Dec 26 '14 at 12:02xrefandnotes2bib. The latter seems a bit more manual, but definitively a plausible workaround. Thanks. – Serguei Dec 26 '14 at 15:24xref. Anotes2bibsolution is a bit more manual, but not much more than your example above, I would have thought. – moewe Dec 27 '14 at 05:51
