Because the novels are actually licensed people don't translate them and put them online. You can pick them up for about £6/$10/€8/lots of Hylian rupees. Personally I'm waiting for the entire series to be licensed before buying them all in 1 go.
I've seen a few of the things but about 95% of that is unwatched. Gotta keep stocked up, I mean who knows when the internet will blow up?
From the season just gone I am planning to watch Natsuyuki Rendezvous, Rinne no Lagrange 2, Jinrui wa Suitai Shima****a, Oda Nobuna no Yabou, Binbougami ga! and maybe that Kokoro Connect thing. None of these are right at the top of my list though so it wouldn't be surprising if I still haven't seen them this time next year.
