For the occasion of Hans Kelsen's 90th birthday, the Austrian federal government decided on 14 September 1971 to establish a foundation bearing the name "Hans Kelsen-Institut". The Institut became operational in 1972. Its task is to document the "Pure Theory of Law" and its dissemination in Austria and abroad, and to inform about and encourage the continuation and development of the pure theory. To this end it produces, through the publishing house Manz, a book series that currently runs to more than 30 volumes. The Institut administers the rights to Kelsen's works and has edited several works from his unpublished papers, including "General Theory of Norms" (1979, translated 1991) and "Secular Religion" (2012, written in English). The Institut's database is free online with login registration. The founding directors of the Institut, Kurt Ringhofer and Robert Walter, held their posts until their deaths respectively in 1993 and 2010. The current directors are Clemens Jabloner (since 1993) and Thomas Olechowski (since 2011).
