my friend, on airport road, take a taxi drive to the airport and take flight to Dubai and got to Kinokuniya in Dubai Mall (order them online so you can pick them up when you arrive). Alternatively, order books through amazon and get them delivered through aramex. Alternatively, buy yourself an ebook reader and download the books online. Or, maybe start a bookshop yourself as there is NO decent bookshop in Doha for the time being.
