Where can I include links to online publications in the common app?

I’ve been published in a couple newspapers and wanted to share my publications with the admissions officers. I’ve included my writing of articles for various publications in the activities section but if I wanted to link some articles for them to refer to where on the common app can I include these links. I’ve also started my own podcast and wanted to know where I could link that if possible. Thanks!

(I am on the Common App FYI)

I would put them in “Additional Information” section.

You would do this in “supplementary materials”. Some colleges call it an “arts supplement” – using a braod definition of “arts.” Same place where musicians, dancers, and visual artists upload their stuff. Here’s an example of the instructions, from Princeton. Note that it says you should not submit journalism.

Some colleges have a different process for writing samples. Here’s an example from Hamilton:

Read the instructions CAREFULLY for EACH college. When in doubt, contact the admissions office.
