I'm afraid to say that the Fact Files weren't in every UK newsagent, in the town where I grew up, only one out of eight at the time newsagents stocked the magazine and the only reason they had it was because my father put it on subscription for me.
As is normal for a part-work that goes several years past its scheduled run. All
newsagents carried it for the first few weeks/months - and all newsagents had access to it - then regular customers put in their standing order. I had to switch newsagents at one point, and lining up the end of one standing order with the beginning of the new one was tricky. I did know of one newsagent who refused to do standing orders, and he used to wonder why he still got in two issues every week, because they'd get mangled on the shelves.
They also didn't really have a high abundance of Andorian features, but that's by the by.
They even got a cover!
But my point is, Andorians were certainly as well represented in previous works as they could be. They were barely in 24th century ST
, so they weren't well represented in that era's publications.
BTW, I still never got that PM, nor a reply to mine. Could you please resend?
