I am trying to switch to http://www.latextemplates.com/template/masters-doctoral-thesis in my masters thesis, and suddenly my bibliographic references are breaking everything, despite working fine before.

A MWE is: download the template, then

First, (in main.tex) Add Hi\cite{foo}. below \pagestyle{thesis}

Second, (in example.bib) Add

 title = {foo},
 howpublished = {\url{foo%x}},


Compile/bib/compile. It will give

Runaway argument?
{\url {foo\field {title}{foo} \endentry \par ...
... File ended while scanning use of \field.

i.e. the % will have been replaced with \field etc etc etc.

How can I stop that from happening?

    You are doing it wrong. The url belongs into the url field url = {[Bibtex and percent sign](http://tex.stackexchange.com/q/319504)}, This can also be seen in the example bibliography – Johannes_B Jul 15 '16 at 8:17

    By the way, your MWE is great ;-) – Johannes_B Jul 15 '16 at 8:18

    You should use the online entry type, by the way. Details can be found in the biblatex documentation. – Johannes_B Jul 15 '16 at 8:25
  • Thank you!! I thought I tried that though. – Kalle Jul 15 '16 at 8:29
  • @Johannes_B Do you want to jot down an answer? Or do you know a good duplicate? – moewe Jul 18 '16 at 12:17

Use the url field, as is shown in the exammple bibliography and as is explained in the documentation of biblatex. By the way, i recommend biber to do the sorting instead of BibTeX.

If your entry is solely an internet source, use the online entry type.

        author  = {many},
        title   = {Percent sign},
        url     = {https://en.wikipedia.org/wiki/%25},
        urldate = {2016-07-18},
        author  = {Kalle},
        title   = {Bibtex and percent sign},
        url     = {http://tex.stackexchange.com/questions/319504/},
        date    = {2016-07-15},
        urldate = {2016-07-18},

\addbibresource{\jobname.bib}%jobname NICHT ersetzen


  • @moewe I also wanted to add a screenshot, but my browser doesn't want to work right now. :-/ – Johannes_B Jul 18 '16 at 12:44
