I have seen sentences without articles in notes and signs. I'd like to know rules regarding when to omit them. Can I simply omit all of them? Here is my example.
"This serial title should be re-cataloged as (a) monograph: (the) subtitle, indicating (the) publishing group's 30th anniversary, is inappropriate, given that (the) succeeding issue celebrates (the) 40th anniversary."
Another question is what level of informality does the omission of articles give to those reading?
Thank you very much.
