What I want to know is what were the popular themes, lengths, and such of any particular time. What were the hot sub-genres. What were people buying? And more importantly, what were they passionate about?
Personally, I felt left behind with the fantasy market in the 80's and I haven't caught up since. Maybe I'll just go back and read stuff from the 70's just to double-down on my out-of-date style.
Had some fun over at Goodreads going through the best-of's for some years. Yeah, I am definitely a 70's child. I saw many books there that I had forgotten that I'd read.
