Should online magazines delete old articles?

It’s usually a bit of a no-brainer to occasionally audit content and remove/redirect content that’s old, no longer relevant, and doesn’t have much value otherwise. However, this is the first online magazine client that I’ve dealt with.

I tried doing some research on my own for the best way to treat archival content, but I didn’t really get anywhere. Just wondering what others have done in this situation.

If I had to guess, my current thoughts are to noindex pages with no value and remove them from the sitemap, but still leave them on the site. Thoughts?
