It was very interesting and funny to view a post on Alexa’s blog see link : http://alexaslodge.wordpress.com/2012/02/27/new-aggressive-book-return-policy/ about an agressive approach taken by a librarian (in a comic strip) to have a client return a book (she kidnapped her son!).
Although, such an idea may pop into our heads in a comical sense it is serious to note that in various libraries around the world many materials are lost (amounting to huge sums) due to persons not returning them. Thus, many libraries have been forced to take drastic actions such as issuing citations and warrants for arrests which may leave some clients dazzled and some library staff feeling apologetic.
