Research Paper Submission?

So I’m a published author (pretty big scientific journal in my field) and I’m wondering how I can send this paper to Stanford? School’s like Columbia ask if you have any research papers you wish to submit and other’s have a portal with upload links.

For now it’s listed in the Additional Info section of the common app (the paper’s exact name and journal), but is it beneficial if I can send them the actual thing?

From last year info: Stanford doesn’t read/allow you to submit/evaluate research papers. They don’t even let you submit the abstract. I guess they have enough info in the application/recos to evaluate.
