The Plainism Institute has been mailing Modern Living Quarterly to subscribers since 1953. The subscription process is straightforward. You provide your information. We add it to the list. The next issue arrives when it arrives, which is quarterly, which occurs four times per year, as is the nature of things that are quarterly.
We do not offer a digital-only subscription at this time. Robert does not feel the quarterly is suited to a screen, and he has editorial authority over this decision. The issue may be read on a screen if one has received it physically and chosen to photograph it. This is, in Robert's view, an adequate workaround.
