Heather,
We charge the cost to replace for a lost map, so the fine will vary widely based on the map they borrowed. We do lend GPS units, for a lost one we charge the price of the unit.
I do take into account how costly both of these things can be, so with the GPS units I charge the cost of that version and not replacement (as tech changes quickly). We do allow our users to replace a lost item with a like copy, so if they lost a map/book/etc.
and find a copy on eBay or through some other vendor that is less then the fine we charge we will accept the like copy, if it is in good condition.
This is our policy across the Libraries and collections, it does put leg work on us to determine value of lost items. However when a student sees a $500 fine on their account for a map it gets returned fast.
