Proper usage of the abbreviation Ms.

I was double checking to find out whether or not to use a period when using the abbreviation Ms. I also found the following info regarding the correct usage and thought perhaps I should share it with you. I know there are others who may not be familar with it.

Some people think of Ms. or Ms as a very recent invention of the women’s movement, but the term was first suggested as a convenience to writers of business letters by such publications as the Bulletin of the American Business Writing Association (1951) and The Simplified Letter, issued by the National Office Management Association (1952). Along with many others, champions of women’s rights saw the virtues of the term and soon advocated its use in more general contexts, as is evidenced by the founding of Ms. magazine in 1972. 

The form Ms. or Ms is now widely used in both professional and social contexts. Thus the term stands as a highly successful language reform—probably because people value its usefulness. As a courtesy title, Ms. serves exactly the same function as Mr. does for men, and like Mr. it may be used with a last name alone or with a full name: Ms. Jones; Ms. Miriam V. Jones. 

Using Ms. obviates the need for the guesswork involved in figuring out whether to address someone as Mrs. or Miss: you can’t go wrong with Ms. Whether the woman you are addressing is married or unmarried, has changed her name or not, Ms. is always correct. And the beauty of Ms. is that this information becomes irrelevant, as it should be—and as it has always been for men. 

Of course, some women may indicate that they prefer to use the title Miss or Mrs., and in these cases, it is much safer to follow their wishes.  ~Howdy
