We both can all search in the school premises. it can however be in the school premises. we could give a circular in the whole school that there is a book lost. we can assign some mentor, or badge holders or prefects, captains and vice captains to go all over the school and search for the book. we would tell them to spread all over the school in order to find ou the lost book. we can also give out a notice on the bulletin board that there is a book lost inside the school. we would pass on the messages to all the teachers and bhaiyyas and didis of the school that there is a book lost in the school. we would also inform the librarian that the book has been lost . hope u all find it good.
