Retirement age of Librarians

It is very sorry to see the notification of MHRD that the retireemnt age of Librarians has not been raised to 65 on par with other teachers. The reason for non raising the age is a silly one. If the reason is a true one why the librarian post in most of the university libraries are kept vacant and unfilled. If sufficient number of qualified persons are available why for so many years the posts are kept unfilled. It is a highly condemnable one.
