"Yes, sort of," Anvar says, willingly enough. "There wasn't a record of my father's fyel arriving, but I thought maybe it got written down in the wrong place, or something."
"That is a good thought. I did not check any other records when your mother asked."
Anvar looks down. "I haven't found anything yet, though."
"It would be worth looking at other aspects of the situation."
"What do you mean?"
"There was no conflict at the Great Library at the time your father was sent here. The records of food usage should let you calculate how many people were housed in the Great Library and whether there was an increase corresponding to the fyel size."
