Is it OK to drop the periods in abbreviations?

I don't understand when or where to use or discard a period when writing short forms.

For example, my college is the Malaviya National Institute of Technology. Should I abbreviate it as M.N.I.T. or is MNIT better?

A second example, for Windows Portable Executable, is it "P.E.", "PE", or "PE."?

Lastly, if I write out my project's name UNMP, should I capitalize all words or just the first one? "Unified Network Management Platform" vs. "Unified network management platform".

I often have this question when writing papers/resumes.

  • @jwpat7 thanks!..I couldn't find before posing my question. And my question is bit different too. Jan 6, 2013 at 10:34
  • Tip: In the question, I would write "Windows", "capitalised", "paper" and "résumé" (or "CV").

You're looking for Punctuation in abbreviations:

  1. In both British and American English, if you are using initial (i.e. first) letters to represent words, you don’t normally need to put a full stop after them:



  2. In American English, however, it is common to use a full stop as an alternative style for certain abbreviations, in particular:

    USA or U.S.A.

So in your case, MNIT and Windows PE are fine. Also, I would capitalize the first words in those abbreviations: United Management ...
