There has been some talk recently on the ILL listserv about customs labels. It appears that when we put the actual value of an item on the label (ie: $75.00), the receiving library has to pay more money to get the package through customs. Several Canadian libraries have complained about this.
It seems that many libraries now write: $0 value and “Library Materials No commerical value” on the slip. This evidently speeds the package through customs. I have created a dummy package with dummy slips and have put it in the back room.
