User blog:Star runner/Codex Astartes

Hi All

I'm pretty new to Warhammer 40k and I've only just got into the novels in the last year or so and I love them. I haven't started gaming yet but I intend to. I read a lot about the Codex Astartes, but is there an actual copy of it anywhere that can be bought or downloaded? I know there's a brief one on here but in the books they talk about it all the time so it must be a large piece of work. Anybody?
