Depends on your field, but my local library has the latest Cell, Science and Nature magazines for perusal, and anything older than 1 year is usually released gratis. If you need more than this to stay up to the state-of-the-art, chances are your future "industry" job will also have access to this, or it will become more of a hobby.

Just my opinion as a PhD, working in industry, who does not read nearly as much as he used to.
