In the description of the UpdateNotForLoanStatusOnCheckout system preference, the sentence: "When an item is checked out, if the not for loan value on the left matches the items not for loan value it will be updated to the right-hand value" should be corrected to "When an item is checked out, if its not for loan value matches the value on the left, then the item's not for loan value will be updated to the value on the right".
