# How to solve 'I found no database files--while read file something.aux'

Hi I am trying to include references into my paper but it keeps showing the following when I compile. I am using texstudio. Message: I'm skipping whatever remains of this command The style file: plain.bst I found no database files---while reading file term paper.aux Warning--I didn't find a database entry for "Astrov"

My code is like this:

\documentclass[letter,scriptaddress,twocolumn, prl,showkeys]{revtex4}

\usepackage{amssymb, amsmath, amstext, amscd, verbatim, mathtools, graphicx, float, caption, subcaption}
\usepackage[utf8]{inputenc}
\usepackage{natbib}
\begin{document}
This is my reference\cite[1]{Astrov}.
\bibliography{term paper}
\bibliographystyle{plain}
\end{document}


• So you have term paper.bib in the same folder? Avoid using spaces in filenames; rather use term_paper.tex, term_paper.bib, ... – Werner May 16 '14 at 6:12
BibTeX doesn't accept spaces in file names. I don't think anybody would touch the sources to make it “modern style”, so there's nothing to do except removing spaces from .bib file names.
