Can anybody post the light novel of Log Horizon please?

Sadly, it was taken down from Baka-Tsuki since it's been licensed by Yen Press for an official, commercial translation.

However, you can find Volume 1, 3, 4, and 5 as epubs here: http://kanakoslightnovels.blogspot.ca/2014/02/log-horizon-volumes-1-to-6.html
Volume 6 is also in the comments. Volume 2 was DMCA'd. I did find a PDF of volume 7, though: http://www.mediafire.com/?27ahvlzq22o2yyi/

Alternatively, you can read them all in your browser at the translator's site: http://skythewood.blogspot.sg/p/prologue-edit-naotsugu-pay-attention-to.html

Aaand, that's all I could find with a google search. Hopefully somebody else can help you better.

By the way, next time post your requests in the request board: http://www.vn-meido.com/k1/index.php/board,16.0.html
