records containing personal documents relating to a Security Service (SB) officer, organised and divided into three parts. Part I contained documents related to the officer's admission to the service: application for admission, personal history, detailed personnel questionnaire and recommendations, if any. Part II contained documents produced as part of a special check to verify a person recruited into the service: enquiries to the relevant SB records and operative divisions regarding the officer and their family and information gathered. Part III contained documents relating to the service record, starting with a form in which the following data were entered separately: the officer's personal details, positions and functions held in sequence, pay grade and secondments, any disciplinary penalties and information on their expungement, awards, periods of leave. Apart from the form, Part III contained applications of an officer's superiors for transfer, change of position and/or promotion, applications of an officer related to their service, opinions of superiors, disciplinary documentation, orders concerning personal record of service, applications for decorations and awards, as well as the text of a pledge signed by an officer, documentation on health status, an officer's obligation to secrecy after leaving the service, pension documentation. As a rule, information about the operative work carried out by officers (i.a. agents and cases managed) was not included in their personal files. "Officer personal files" were kept by the Personnel Department of the Ministry of the Internal Affairs (concerning employees of the Ministry of the Internal Affairs) or the respective personnel divisions of the Security Service field units; after the termination of the officer's service, they were archived by a "C" division competent for the SB unit in which the officer completed service or Division IV of Bureau "C" of the Ministry of the Internal Affairs in the case of officers who completed service in units of the Ministry of the Internal Affairs. Files were labelled with an archive number consisting of the serial number of the archive journal followed by the journal symbol after the slash: V (Security Service), VI (Citizens' Militia), VII (civilian employees of the Ministry of the Internal Affairs), VIII (soldiers of the Ministry of the Internal Affairs).
