SCOPUS is an abstract and indexing database.
This means it does not have the full-text of everything in SCOPUS.
However, you may often be able to access the full-text of the item you need via a different full-text database or electronic journal subscribed by the library.
So how do you check to see if you can download the full-text of the article you want?

If you do not find the full text, try pasting the title into Google Scholar.
If you still do not find it, use Interlibrary Loan to make a free request.
