Hi,

Could someone let me know which one of the following plural forms of abbreviations is more common in the English-speaking community:-

a. CDs

b. CD's

And, if we have to turn them into possessive adjectives, how should we write them?

Thanks.

Kathy

Hi Kathy,
I would say CDs is more common in the U.S.
To make it possessive, you would then make it CDs'.

If you want the gory details, you can surf the web yourself. I've pasted below a section from:

Whether to add an apostrophe for a plural where the plural is not formed by doubling up the last letter: should one write CDs or CD's? The apostrophe is not needed grammatically but sometimes is added to make it clear that the s is not part of the abbreviation. Because the apostrophe most often represents possession or a contraction, some style guides prefer that it not be used at all with abbreviations, but only with individual letters—"Dot all your i's and cross all your t's!" or "Mind your p's and q's!"—or numbers—"The dyslexic student mixes up his S's and 5's." Thus numbers, such as decades, that are understood to represent other concepts, are not written with apostrophes either—e.g., "The U.S. enjoyed an economic boom in the 1990s and the Roaring ’20s", referring to decades, or "I am going to the bank to exchange four 5's for two 10's", where the 5's and 10's refer to banknotes.

CDs' is plural possessive.

But for one CD is it CD's, such as in the sentence, "That CD's surface is scratched."
Hi, I have a question for using abbr. on the plural form.

Many research articles used IS for "Information Systems" , instead of ISs. Is it OK?
What about Computer Systems (CS) or CSs?.
Thanks

Note : an Information System (IS) - is any combination of information technology and people's activities using that technology to support operations, management, and decision-making.

Information Systems (IS) -s an academic /professional discipline bridging the business field and the well-defined computer science field that is evolving toward a new scientific area of study.

sometimes I found as Information System(s) (IS)..

Hello Kathy !
the correct plural form of any abbreviation is 's. in this case CDs is the correct one. they cannot be changed into possessive adjective. for example you cannot write CD's cover, it is wrong rather you can write 'the cover of CD' or simply 'CD - cover'
you are most welcome kathy
