Kartoteka ogólnoinformacyjna (KOI) (General information card-index) card-index of ongoing and closed Security Service (SB) operative procedures. The general information card-index was kept by Division III of Bureau "C" of the Ministry of the Internal Affairs (division "C" of local units) and mainly consisted of EO-4-A index-cards concerning current operative activities (they contained personal data of the person of "operative interest" and information on the registration number and the unit managing the case) and E-14 (E-14/1), concerning closed operative cases and personal information sources (osobowe źródło informacji, OZI) eliminated from the agent network (they contained complete personal details of the registered person, category of operative case or cooperation, reasons for terminating the case or eliminating the collaborator from the agent network, unit managing the case and the archival reference number). ‘Securing’ measures of Department I of the Ministry of the Internal Affairs were also included in the KOI to eliminate the possibility of uncontrolled registration of the "operative interest" by another SB unit in a specific person. The KOI of the Ministry of the Internal Affairs also included information on persons registered "actively" by the Internal Military Service (WSW – military counter-intelligence), WSW of the military units of the Ministry of the Internal Affairs, Reconnaissance Division of the Border Protection Troops, Second Directorate of the General Staff of the Polish Armed Forces (military intelligence) and on persons registered as allowed access to secret documents, persons who were forbidden to travel abroad ("restricted", restriction, foreign travel restriction), persons under investigation, etc. The general information card-index of the Ministry of the Internal Affairs was also known as the Central General Information Card-Index because, in addition to registrations made by units of the Ministry of the Internal Affairs, it included information on registrations by Department I of the Ministry of the Internal Affairs and other above-mentioned services of the apparatus of terror, as well as index-cards concerning persons registered by the SB territorial operative units. Each "C" division of a SB field unit kept its own KOI, containing index-cards relating to registrations made exclusively by the operative cells of the relevant SB territorial unit.
