Here some more info from the Lost and Found team: If we find library books, we will not post them but return them to the library. They get booked off the account (text books same as pleasure reading). Please check your account or contact the library. Any music item will be handed over to the VIP office. Please ask there, if you are missing an instrument or scores. If valuables were lost/forgotten during sports lessons, please check with the sports office, too. Sometimes they will keep these items for a short period of time before they will be brought to the school shop. Now we have ID cards! And they get lost!!! Primary parents, please write the class on the back of the card, so we, the Lost and Found team, can return the cards directly! If other people (students, support crew, etc) find cards, they will be handed to the school shop first, like all other valuables.
