Print bibliography: Empty bibliography

It’s been days I’ve been looking for a valid solution, but it just never works.

The minimal reproducible example is the following:

\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{csquotes}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage[authordate,autocite=inline,backend=biber,sorting=nyt,]{biblatex-chicago}
\addbibresource{Test.bib}
\usepackage[left=2cm,right=2cm,top=2cm,bottom=2cm]{geometry}
\DeclareUnicodeCharacter{202F}{\,}
\begin{document}

Test citing \citep{sanborn_learning_2014}

\printbibliography
\end{document}

The Test.bib:

@article{sanborn_learning_2014,
    title = {Learning Democracy: Education and the Fall of Authoritarian Regimes},
    volume = {44},
    issn = {0007-1234, 1469-2112},
    url = {https://www.cambridge.org/core/product/identifier/S0007123413000082/type/journal_article},
    doi = {10.1017/S0007123413000082},
    shorttitle = {Learning Democracy},
    abstract = {Studies on what causes a state to democratize have focused on economic, social, and international factors. Many of them argue that higher levels of education should promote democracy. However, few articulate clearly how education affects democratization, and fewer still attempt to test the supposed link across time and space. This article fills that gap by considering how different levels of education influence democratization, and the conditions under which education is most likely to promote democracy. Analyses of eighty-five authoritarian spells from 1970 to 2008 find that higher levels of mass, primary, and tertiary education are robustly associated with democratization. Secondary analyses indicate that education is most effective in promoting democratization when both males and females are educated. An illustration from Tunisia follows.},
    pages = {773--797},
    number = {4},
    journaltitle = {British Journal of Political Science},
    shortjournal = {Brit. J. Polit. Sci.},
    author = {Sanborn, Howard and Thyne, Clayton L.},
    urldate = {2021-09-18},
    date = {2014-10},
    langid = {english},

The warning message when not citing in the text is LaTeX Warning: Empty bibliography on input line 16.

The error and warning messages when citing in the text are: On line 14: ! Undefined control sequence. ! Missing $ inserted. ! Extra }, or forgotten $. On line 15: ! Missing $ inserted. On line 16: LaTeX Warning: Empty bibliography on input line 16.

I’m running on Linux, Texlive2019 (apt installed that one, not a more recent one) and texmaker on Ubuntu 20.04.

Anyone has a solution?

Solution

  • Two problems:

    • the } at the end of your bib entry was missing

    • \citep{} is not provided by biblatex by default. You can use \parencite{} instead or the natbib=true option of biblatex
