I have noticed that BibTeX will change the initials "U.S." (as in "United States") to "U.C." This has happened using both IEEE and Elsevier document classes, and it works the same with and without punctuation. This happens formatting the citation as either @misc and @techreport (it may also happen with additional formats, but I have not tried).

For example, when attempting to cite

"U.S. Census Bureau"

the output becomes

"U.C. Bureau"

Here's a code sample.


Citation \cite{census:2011}.



with BibTex entry:

  author        = "U.S. Census Bureau",
  title         = "2010 Census",
  howpublished  = "U.S. Department of Commerce",
  month         = feb,
  year          = "2011",


[1] U. C. Bureau, 2010 census, U.S. Department of Commerce (Feb. 2011).

I can use \verb to force the correct lettering, but the resulting font and font size is different than the surrounding text. How can I correct this in a citation?

Is this some well known inside joke I'm not in on?

Can you post a minimal working document that shows the issue? – Alan Munn Feb 11 '13 at 22:13
I wrote the same thing as the accepted answer as a comment but then deleted it as that would explain U C Bureau But you claim to have got U C Census Bureau with both C and Census assuming that is a typo in your question could you edit it for future reference. – David Carlisle Feb 11 '13 at 22:58
@DavidCarlisle Fixed. – Chance Feb 11 '13 at 23:23
In addition to Tyler's answer below, you should write U.S.~Census Bureau (and U.S.~Department of Commerce) in order to prevent the space after the second full stop from being enlarged. – kahen Feb 12 '13 at 0:03
@kahen Thanks for the tip. – Chance Feb 12 '13 at 1:47

BibTeX is likely interpreting U.S. Census Bureau as a personal name, and abbreviating U.S. to U. and Census to C. You need to wrap the whole name in {}:

author = {{U.S. Census Bureau}},

That corrects the issue. Thank you! – Chance Feb 11 '13 at 22:31
