For the environmentally-conscious reader, Digital-magazine store Zinio is currently offering free subscriptions to select publications as part of its “Read Green Initiative.”

There are several magazines to choose from in many categories. The sign up process is very simple: just select your magazine and provide an email address, then sign up for a Zinio account (if you do not already have one) with that same address.

Once you’re logged in to Zinio, your library should have your new magazine available to read. You can read it in your Flash-enabled browser or download the magazine to read offline using the free Zinio Reader (Win/Mac). I recommend downloading the reader so as not to tax the browser’s resources; The image quality is better as well.

Since you like to score free publications, you may also want to try Wowio.
