How to count 'newspaper'?

[Heidi]

Dear teachers,

I have two qustions about the word 'newspaper'.

#1 Are there any mistakes in the following dialog sentences? Please help me correct them:
- Do you have today's newspaper?
- No, I' sorry.
- I'll go buy a newspaper.

#2 When we say 'a newspaper', what do we mean? A piece of paper or several pieces of paper together?

Sounds fine.

It means one entire issue of a newspaper.

Today's copy of The New York Times - that's what you could mean if you say "buy a newspaper."

I suppose if you are incredibly wealthy, it could mean you are going to buy the entire publishing company. That's not the normal meaning.
