Here last(2009-10 )stock verification report in my library i have found 139books lost from my library.we are following open access system in library and most of the student are higher secondary and degree level.: When the average attendance in the library is about 200 to 300 daily, then it is quite obvious that some student may do such type of misdeeds. But can you suggest me how i can convicts my authority about the matter. Is there any rule about library book lost. There is no security system but I have inform authority about it . I would like to quote Dr Ranganathan, the father of Library Science in India that “It is better to loose a book than to loose a reader
