Bibliography not changing from German to English while citing

Question

I am using a template from my university for my thesis. It was initially in German. I changed it completely to English. The Bibliography had the title set to 'Literaturverzeichnis', I changed the language settings in the Preamble, and it now says 'bibliography', but when I cite my references in the body of the document, it still uses German - like XYZ u.a instead of XYZ et al, or uses German labels - Bericht etc instead of report. I cannot find the setting. Any help would be appreciated. Thank you. I have attached the code snippet and picture of output. As seen, it uses German 'und' instead of English 'and'. I have also included a code snippet from the Preamble which i think is relevant to the setting. I have tried permutations such as removing the German or changing the order, but to no avail.

\cite{energiewende2017} state that Germany must reduce its emissions by 95\% by the middle of this century. Gradual phaseout of almost all nuclear and coal fired power plants is also to take place in the next few years. Of the world's three biggest Carbon Dioxide emitters, China and India are fully committed to transitioning to low-emission sources of energy to tend to the energy needs of their billion-plus people.

Answer 1

The OP has stated in a comment that he/she uses a bibliography style called dinatles and has made the file dinatles.bst available online.

Assuming one needs to keep using this bibliographic style file and merely wishes change the language-specific settings from German to English, I suggest one proceed as follows:

• Make a copy of dinatles.bst and call the copy, say, engdinatles.bst. (You are obviously free to choose another name.)

• Open engdinatles.bst in a text editor. The program you use to edit your tex files will do fine.

• Go to line 109 of the file and change all German-language strings to equivalent English-language strings. E.g.,

  FUNCTION {push.bd}        { "vol." }
  FUNCTION {push.diplom}    { "Master's Thesis" }
  FUNCTION {push.disser}    { "Doctoral Thesis" }
  FUNCTION {push.forschung} { "Technical Report" }
  FUNCTION {push.hrsg}      { "Ed." }
  FUNCTION {push.in}        { "In:" }
  FUNCTION {push.isbn}      { "ISBN" }
  FUNCTION {push.issn}      { "ISSN" }
  FUNCTION {push.kap}       { "chap." }
  FUNCTION {push.nr}        { "nr." }
  FUNCTION {push.sn}        { "pages" }
  FUNCTION {push.s}         { "pp." }
  FUNCTION {push.siehe}     { "see" }
  FUNCTION {push.ua}        { "et~al." }
  FUNCTION {push.und}       { "and" }
  FUNCTION {push.url.name}  { "URL" }
  FUNCTION {push.veranst}   { "Event" }
  FUNCTION {push.von}       { "by" }
  FUNCTION {push.zugriff}   { "Accessed on" }
  

  Happily, the author of dinatles.bst showed sufficient foresight to centralize all language-specific settings!

• Save the file engdinatles.bst either in the directory where the main tex file is located or in a directory that's searched by BibTeX. If the latter option is chosen, be sure to also update the filename database of your TeX distribution suitably.

• In the main tex file, change the instruction \bibliographystyle{dinatles} to \bibliographystyle{engdinatles} and perform a full recompile cycle -- LaTeX, BibTeX, and LaTeX twice more -- to fully update all items.

• You should keep loading the natbib citation management package, but you probably no longer need load the babelbib package.

Happy BibTeXing!
