I followed this and can grab stuff (with Google Scholar) and put it in my ref.org, as described. However when I create a testbibtex.org with this lone line:
\bibliography{ref} all I get with Latex export is the word "Contents." I've copied the contents of ref.org to ref.bib, entries such as this:
@book{burton2006elementary, title={Elementary number theory}, author={Burton, David M}, year={2006}, publisher={Tata McGraw-Hill Education} } but nothing of this is included in the Latex export. So, yeah, I really need a beginner's tutorial in this whole process.
