Do you mean they don't have an accurate count because they took the books? Surely they counted another way.
I think they can keep an accurate count just by how many bus trips they made... then add Kerry, who was too important to wait on a bus...
I think the lack of buses and the general slowness reduced the number of people who were able to pay their respects. Mind you, this was just during the early morning today; at all other times, it appeared to be a wonderfully well organized system.
The guy handing out the flyers telling people what not to bring to the library noted that whereas he had been going through cases of flyers around 10pm, at 1am he was handing out far fewer per hour.
Around 3am, a great many people had just given up and left.
