Changes to capitalization in .bib file not reflected in output

Question

In reviewing my document I found errors in capitalization of some acronyms in titles of references (dc or Dc instead of DC, etc). When I corrected the .bib file, changes were not reflected in the output. If I make more substantive changes (adding/removing words) they are reflected.

I am using BibTeX, MikTeX, and TeXstudio with:

\documentclass[conference]{IEEEtran}

to set up the document class.

And this call for building the bibliography:

\bibliographystyle{IEEEtran}
\bibliography{ref}

Here's an example reference entry in ref.bib:

@article{patterson2012:green_building,
  title={DC, come home: DC microgrids and the birth of the `enernet'},
  author={Patterson, Brian T},
  journal={IEEE Power and Energy Magazine},
  volume={10},
  number={6},
  pages={60--69},
  year={2012},
  publisher={IEEE}
}

And the output:

As others with similar problems attempted, I deleted all temp files (aux, bbl, blg, log, and gz) then compiled twice - but this didn't work.

Answer 1

You can either enclose the full title in double curly braces:

title={{DC, come home: DC microgrids and the birth of the `enernet'}},

or put them around the individual letters you want to have capitalised:

title={{DC}, come home: {DC} microgrids and the birth of the `enernet'},
