# How to force phdthesis bib entry to expand to Ph.D. (and not to PhD) in the bbl?

The bib entry:

@phdthesis{w-ieaem-07,
author      = {Ron Wein},
title       = {The Integration of Exact Arrangements with Effective Motion Planning},
school      = {Tel Aviv University},
year        = {2007}
}


expands to:

\bibitem{w-ieaem-07}
R.~Wein.
\newblock {\em The Integration of Exact Arrangements with Effective Motion Planning}.
\newblock PhD thesis, Tel-Aviv University, Israel, 2007.


in the bbl file. How can I enforce

\newblock Ph.D. thesis, Tel-Aviv University, Israel, 2007.

Welcome to tex.sx! A tip: If you indent lines by 4 spaces, then they are marked as a code sample. You can also highlight the code and click the "code" button (with "101010" on it). –  Andrey Vihrov May 11 '11 at 19:35

It seems that you are using the standard \bibliographystyle{plain} command. In this case there's little you can do, since the PhD is hard wired into plain.bst.

A solution is to copy the file plain.bst as, say, xplain.bst in your work directory, edit it to change the (unique) string PhD into Ph.D. and call

\bibliographystyle{xplain}


  type = {{Ph.D.} Dissertation},
