I have a problem using Biblatex/Biber. First I used:


Everything worked fine. Then, I wanted to change the style to chem-acs. This gave me the warning: Empty bibliography.

Tried changing the style to authortitle, this didn't give me the error. What am I doing wrong? Thank you!

Info: MacOSX version 10.11.5, Texmaker version 4.5

    Try deleting the temporary files (.aux, .bcf, .bbl) and recompile from scratch. If the error keeps coming back, please try and provide an MWE. Have a look at the .log and .blg files.

  • Thank you! I only deleted the .bcfand .bbl files and then compiled it again. Deleting all three files solved the problem :-)

This is a subtle one: it's caused by the change of sorting order between the standard styles and the chem-acs one. The standard styles do sorting = nty, the ACS one sorting = none. This causes some issues with data left in the .aux file, which is where the error comes from. (You can see the issue by simply adding sorting = none after a LaTeX/Biber/LaTeX cycle with no style explicitly loaded, as that does sorting = nty implicitly.)

As noted in a comment, deleting the .aux, .bbl and .bcf files (or simply ignoring the error, getting to the end of the run and re-running Biber) clears the issue. However, this should at the very least give a better error message: I've logged in the biblatex issue tracker.
