Abstract: Biographical dictionaries of communist repression in Romania may be described according to the following elements: 1. The way in which sources (books, journals, oral history, state archives, private archives) are used and displayed either at the end of the volume, in notes or within each biographical sketch. 2. The pattern of the biographical presentation which is supposed to establish a set of expectations concerning the order and coherence of each biographical sketch. 3. The regional dimension limits the list of names to a geographical area while the occupational profile describes former political prisoners belonging to a particular class (church, army, medical profession). 4. The chronological frame which may overlap with the whole communist period (1945-1989) or certain periods determined by the activity in a particular political prison (Sighet). 5. The style and tone of the biographical presentation may be influenced by vision, personal experience and political orientation.
