# How to achieve full compression of references with biber and add comments to grouped citations?

I am working on a thesis, where I need to cite a lot of different papers. Following the regulations in my discipline, I need to group citations, i.e., a single number, for example (1) stands for a group of citations:

(1) (a) R. R. Schrock, .... (b) Y. Chauvin, .... (c) R. Grubbs, ....

Also, I sometimes need to add one or more additional comments in the way:

(1) This type of thing is described in: (a) R. R. Schrock, ... (b) Y. Chauvin, .... (c) R. Grubbs, ....That type of thing is described in: (d) R. R. Schrock, ... (e) Y. Chauvin, .... (f) R. Grubbs, .....

How do I achieve this type of referencing? So far I am using the following settings, but they don't seem to match my preferences:

\documentclass[
a4paper,
final,
12pt,
numbers=noendperiod,
BCOR=5.00mm,
bibliography=totoc,
listof=totoc,
]{scrreprt}

\usepackage{csquotes}
\usepackage[backend=biber,
citestyle=numeric-comp,

\begin{document}

Here I am citing a group of papers.\supercite{Person1,Person2,Person3}

\printbibliography

\end{document}


For an example of this reference style see:

There are really two separate things here, one doing 'simple' sub-entry lists with biblatex and the other handling complex note-like citations. As I'll need a demo bibliography, I'll cover both in one example after some explanation.

For the sub-entry lists, you need to use the appropriate mcite-like citation commands (biblatex doesn't add this automatically to the standard citation types). For example, for a superscript multi-part citation you want \msupercite. Unlike mcite you need to provide first a key then the list of entries.

For the complex note business there is no option but to do at least some of the work by hand. The notes2bib will let you run this into your source without too much complexity. What you'll need to do is use \fullcite or similar to place the full bibliographic data where you want it and intersperse the 'other' text. In the following I've reused the multi-part citation so it is automatically a list: for 'richer' cases you'll need to code in the (a), (b) and so on yourself.

As pointed out in a comment, to get the citation to appear only once in the bibliography, a bit more work is needed using the same approach as Exclude \fullcite{...} citation from bibliography.

• When I am trying to make more complex citations, I have the problem, that all references that are mentioned in the notes reappear in the references section, i.e. they are mentioned first in the note and then get a separate citation. Is there a way around this? With your preamble I tried the following: Here I am citing a group of papers.\bibnote[metathesis]{For papers on metathesis, see: (a) \fullcite{Grubbs2003a} (b) \fullcite{Herrmann1999} (c) \fullcite{Nolan2011}} Here I want to cite this group again\bibnotemark[metathesis]. \printbibliography Is there anything wrong the way I do it? – Vlad030691 Dec 22 '14 at 12:24
