In cases where damage or loss of library material occurs, the patron will be assessed the replacement cost. In other instances where library-media materials are retained by the borrower beyond the designated due date, fines will be levied as a sanction to effect the prompt return of items which may be in demand by others. When materials are not returned, or fines not paid, holds are placed on the transcript records of those involved. In extreme cases, when expensive or valuable items are involved, the provisions of RCW 27.12.340 may be invoked.
