I have a problem with my bibliography. Though my bib file is not empty, I get the message that it is. Also my .bbl file is empty.

This is my document:

  \documentclass[10pt, a4paper]{Thesis}





And this is my bib file:

          author = {Author, This},
           pages = {301},
       publisher = {Springer},
           title = {{Book}},
            year = {2010}
  • Welcome to TeX.SX! You're missing a comma at the end of the author line and BibTeX should have warned about the problem.

  • Thank you. Sorry, this was a small error in my minimal example, but not the solution to my problem.

The correct syntax is \bibliography{testbib} (without the .bib ending).


If you don't provide any ~\cite{reference} command in the document file, then this warning will always occur despite having a full bibliography file.
