House registers of Riga Ghetto serve as a significant source of information. These documents contain references to head and members of the family registered at the house, including age, place of birth, occupations and previous and sometimes further place of residence.
The study and research of records of house registers is considered a very complicated task to perform. Even so, the biology teacher of Northern States Gymnasium (Ziemeļvalstu ģimnāzija) Tamara Zitcere has decided to maintain the research to become the unique Holocaust study in terms of its scope and content.
Houses of former Riga Ghetto were separated from the rest of the city with barbed wire; these houses became a shelter for 29 602 Jews forced to leave their initial residences during 1941—1943.
In total, T. Zitcere has overlooked and studied 346 books of House registers at Latvian State Historical Archive, including 68 house registers of Riga ghetto preserved by nowadays. Total number of houses in Riga Ghetto was 81. Upon the research of information and the generalization of data, the list of 5764 Jewish victims of the ghetto was prepared. This list includes the following data: name and last name, patronymic if was specified, year and place of birth, date of accommodation and departure and the place of next residence if specified.
The list of ghetto prisoners may be updated in the future upon the study of house registers of other streets of Riga: sometimes there was an address of further residence in Riga ghetto specified. This approach was used to study the records of house registers of 1941 to identify Jewish residents of Matisa and Merkela streets and Stabu street.
