A paper by Saulius Grybkauskas on "State-Security Clearance as an Instrument of Social Control in the Industry of Soviet Lithuania, 1965 to 1985," originally received on 11 May 2007 is no. 48 in the PERSA series. The paper is available at www.warwick.ac.uk/go/persa. The KGB system of vetting individuals and clearing them for employment in state industry was created to keep the secrets of the Soviet state from NATO intelligence agencies. The paper examines how this system operated in Soviet Lithuania in the Brezhnev period: what work was defined as "secret"; how the KGB organised and sanctioned lists of secret employment positions; how the KGB checked the suitability of candidates for employment in secret work; and how the clearance system also controlled society by limiting the mobility and careers of those identified as politically unreliable. A summary of Grybkauskas's doctoral dissertation, "Industrial Management in Soviet Lithuania, 1965–1985: Tensions and Conflicts," defended at the Lithuanian Institute of History, Vytautus Magnus University, Kaunas-Vilnius, is also available on line from www.warwick.ac.uk/go/sovietarchives/public.
