I'm using Clean Thesis template for my thesis. My problem is: "the references are not compressed," as shown in the highligted line segment in the image below. Could anyone please suggest how the issue can be addressed? Thanks a million.

And, here is the code that configure the bibliography system:

  • What bibliography system is used by your template? – Dr. Manuel Kuehner Sep 7 '17 at 10:04
  • Hi, Dr. Manuel. I'm using BibTeX system. – livyiitc Sep 7 '17 at 10:07

    Please post the code that configures BiBTeX. – Dr. Manuel Kuehner Sep 7 '17 at 10:12
  • % I'm not sure if this is what you asked. \usepackage[ % clean thesis style figuresep=colon,% sansserif=false,% hangfigurecaption=false,% hangsection=true,% hangsubsection=true,% colorize=full,% %colortheme=bluegreen% %colortheme=bluemagenta,% bibsys=bibtex,% bibfile=bib-refs,% bibstyle=numeric%authoryear%alphabetic%numeric%; ]{cleanthesis} – livyiitc Sep 7 '17 at 10:19

    Add it to your question -- not as a comment. Maybe read tex.meta.stackexchange.com/questions/228 first. – Dr. Manuel Kuehner Sep 7 '17 at 10:26

The cleanthesis.sty uses biblatex to manage citations. While biblatex itself offers a broad variety of citationstyles, cleanthesis offers only three of them: alphabetic, numeric and authoryear to choose from using the style=... option from cleanthesis.

In order to use citationstyles other than the above mentioned, one can edit a local copy of cleanthesis.sty in the following two ways:

1. fixed citestyle, not customizable via option

The first customization option is to directly pass the desired citationstyle as an option to biblatex. Consider the following code, which is a copy of line 284-300 from cleanthesis.sty.

\RequirePackage[                    % use biblatex for bibliography
    backend=\cthesis@bibsys,        %   - use biber backend (bibtex replacement) or bibtex
    style=\cthesis@bibstyle,        %   - use alphabetic (or numeric) bib style
    natbib=true,                    %   - allow natbib commands
    hyperref=true,                  %   - activate hyperref support
    backref=true,                   %   - activate backrefs
    isbn=false,                     %   - don't show isbn tags
    url=false,                      %   - don't show url tags
    doi=false,                      %   - don't show doi tags
    urldate=long,                   %   - display type for dates

Replacing style=\cthesis@bibstyle by citestyle=numeric-copm (or every other citestyle biblatex offers) and not using clearthesis's bibstyle=... option in the preamble of the document should work.

2. flexible citestyle, customizable via option

A better and more flexible approach is the following. The following code is again copied from cleanthesis.sty (line 92).


To customize this one could add the numeric-comp style (or any other) as follows:

\define@choicekey*[ct]{cthesis}{bibstyle}[\val\bibstylenr] alphabetic,numeric,authoryear,numeric-comp}[alphabetic]{\def\cthesis@bibstyle{#1}}

Now the added style can be chosen in the preamble of the .tex file using something like:
