The year 2017 is the Quasquicentennial year of Sri S R Ranganathan. SRR is considered as the leading light of library and information science even today.  With the development of ICT and its enormous influence in all areas of library science, it has become a fashion everywhere to sideline SRR studies. But on examining and analyzing his works, it can be seen that the concepts and techniques enunciated by him stands test of the time and remainslive in the ever changing informatics field and society. His works acted as the foundation of the Information Management of the yesteryears, Knowledge Management of the modern-day and shall continue showing light to the future dispensations. They still remain as a source to the practical and theoretical solutions for policies, plans and programmes, innovations, services, systems, networks, etc.  Informatics Studies would like to commemorate his contributions to LIS profession by publishing a special volume at the end of the Quasquicentennial year. Scholars are requested to contribute papers for SR Ranganathan Quasquicentennial Memorial issue of Informatics Studies to be published as Volume 5(1) January 2018. During the centenary of his birth in 1992, numerous biographical and autobiographical materials and collections of essays reflecting Ranganathan’s influence were published. Informatics Studies invite studies, biographical sketches, papers on his views, plans, research, theories, standards, procedures, and programmes correlating with the current developments in the Knowledge management scenario.
