From Edmund Schubert's Letter From the Editor this issue:
Starting this month, IGMS will make the most recently published previous issue free on a rotating schedule. This means that from now on, during the same time that the current issue is live, the entire issue that was published right before it will be free for anyone and everyone to read. For as long as Issue 39 is the latest one out, Issue 38 will be available for free. Then when Issue 40 is published, Issue 39 will be free, and so on. You still need a subscription to read the latest issue, and you still need a subscription to have full access to our entire archive of issues and all the stories contained therein, but we believe in the authors and stories we publish and we want a wider audience to have a chance to sample them. So tell your mother, tell your best friend, tell that co-worker of yours who's a closet SF-fanatic but doesn't want the boss to know; tell everybody: free fiction from IGMS!
