As far as i know ,, and according to the Kuwait international fair company [ KiF ]
The book fair is from 13th till 23 of November

of course i haven’t noticed any ad or even a small bit in the newspapers ( other than some general complaining about banning of books which happen every year ) way to go The National Council for Culture, Arts and Literature
the good part that the NCCAL* have a website and they set a side a section for Kuwait book fair
but its in Arabic [ link ]

* thats the short they used on their home page , i didn’t make this up , i just love the irony that it sound like the Kuwait word nagal نغل which translate into a$$hole
