Unknown quotations mark on APA bibliography

Question

I can't figure out why my bibliography renders weird quotation marks. Sometimes they do not close, sometimes they wrap around a part of the author's name. My document looks like this:

\documentclass[12pt]{amsart}
\usepackage[spanish]{babel}   
\usepackage{csquotes}

\title{Trabajo en base de datos 2: Reseña\\
\large Introducción a la modelación matemática de la naturaleza
}
\author{Fundación Universitaria Konrad Lorenz\\Curso: Cálculo Diferencial\\Estudiante: Jonatan Ahumada\\ Cód.506181029}

\begin{document}
\maketitle
\cite{chejne2016aproximacion}
\cite{knuth2005art}
\bibliographystyle{apacite}
\bibliography{referencias}      
\end{document} 

And my .bib file looks like this:

@article{chejne2016aproximacion,
  title={Una aproximaci{\'o}n a la construcci{\'o}n de modelos matem{\'a}ticos para la descripci{\'o}n de la naturaleza},
  author={Chejne, Farid},
  journal={Revista de la Academia Colombiana de Ciencias Exactas, F{\'\i}sicas y Naturales},
  volume={40},
  number={155},
  pages={353--365},
  year={2016}
}
@misc{knuth2005art,
  title={The Art of Computer Programming, Volume 4, Fascicle 2: Generating All Tuples and Permutations},
  author={Knuth, Donald E},
  year={2005},
  publisher={Addison-Wesley Professional Boston, MA}
}

Furthermore, I made my .bib file pasting the code from GoogleScholar, so I know the .bib is fine. It just seems as if \apacite doesn't know where to open quotations or where to close.

I'm very new to LaTex, any help would be much appreciated.

Answer 1

The apacite bibliography style needs to be used in conjunction with the apacite package. So you need to modify your document like this. I've loaded the apacite package with the [natbibapa] option, which allows you to use natbib citation commands. If you want to use the original apacite commands you can leave that option off. See the following question for some details on the difference:

• What is the relationship between natbib, apacite package, and apa document class?

\documentclass[12pt]{amsart}
\usepackage[spanish]{babel}   
\usepackage{csquotes}
\usepackage{apacite}
\title{Trabajo en base de datos 2: Reseña\\
\large Introducción a la modelación matemática de la naturaleza
}
\author{Fundación Universitaria Konrad Lorenz\\Curso: Cálculo Diferencial\\Estudiante: Jonatan Ahumada\\ Cód.506181029}

\begin{document}
\maketitle
\cite{chejne2016aproximacion}
\cite{knuth2005art}
\bibliographystyle{apacite}
\bibliography{referencias}      
\end{document}

Some comments on your .bib entries. Google Scholar doesn't always provide the best .bib entries; they are sometimes full of errors. In the example you show, for instance, I would preferably use:

@book{knuth2005art,
  title={The Art of Computer Programming},
  author={Knuth, Donald E},
  year={2005},
  volume={4 Fascicle 2: Generating All Tuples and Permutations},
  publisher={Addison-Wesley Professional},
  address={Boston, MA}
}
