Chaper Approved has all the fluff, well had it for the first time. It was the first book out for Warhammer 40,000: Rogue Trader... if I remember I will check when I get home, I don\'t keep mini books from the 80s in my desk.
As for the mini size difference. Biggest place I noticed this was with the Orcs. I took a long hiatus from the hobby. All the orcs I had were from the 80s with just a fwe from the early 90s. I also had a bunch of space orks from when the 4 Ork army books came out (I think it was 4, there was Warrgh, then Ere We Go, then Freebooterz, then they put out a new one that made them all obsolete)... anywah back on topic, I have 3000 or so points of Evil Suns and Bad Moons. Skip ahead to about 2 years ago when GW open a shop in my town and I get back into the hobby, and I pick up the shiney new orcs and goblins minis. Yeah they look great but they are litterally about 2 heads taller, and all muscle. Sure it fits orc but it makes about 8000pts (and how many $).of minis I have look just dumb and small. I was rather frustrated.
I won\'t mention the number of those old minis that aren\'t legal now since the rules have changed 3 times since then....
