Who/where did you get the back issues from? I have a couple that I need to get and didn't know how to go about it. I contacted the company that I subscribed through and they said they didn't sell backs.
I used a form from the magazine. There was a whole page showing the various covers of different issues along with ordering information. I recall that some issues, especially earlier ones, were no longer available, but I managed to get a dozen or so that I hadn't purchased at the bookstore. I don't know about current availability; you might PM Ailsa.
