are they actually talking about books or are they talking about books of matches? I havent been told anything about stipulations of carrying books and I usually carry enough paperwork to start a bonfire

edit: msm: the airports I flew with: if you were coming from outside the airport only clear liquids were allowed and then they had to go through the xray scanner (not sure if different liquids look different through the scanner)... If you were already in the airport and just jumping on another plane or whatever they didnt look twice at the drink because you had to of gotten it from the airport anyway.
