Abstract: In the era of digital development, one of the key activities of archival institutions is the organization of remote access to archival documents. Archives are being converted into electronic form and expand the capabilities of the scientific reference apparatus, independently or jointly with partners they create electronic exhibitions, digital collections, as well as information resources dedicated to the most relevant and in-demand topics. A definite trend in the field of archival business is the development of information systems for remote access to scientific reference equipment and electronic copies of archival documents. Such archival resources are of great scientific and public importance and are of interest to researchers. The main task of the study was to identify regional information systems, describe their capabilities for searching and online access to digitized archival documents.  The research is based on a systematic approach to the study of information resources of the archival industry, the main methods are heuristic, comparative, systematization and generalization. The study consistently examined the official websites and portals of archival management bodies and state archives of the subjects of the Russian Federation, as well as regional genealogical projects created with the participation of archives. The main result of the study was a list of information systems for remote access to documents of regional state archives. Information systems were reviewed by federal districts. The leaders in the field of archival informatization can be called the Central and Northwestern Federal Districts, as well as individual regions (Tyumen, Novosibirsk Regions, Krasnoyarsk Territory). The most promising is the creation of multifunctional information systems that provide a wide range of archival services: from online work with a scientific reference device to a remote order for digitization of any archival document.
The created list of remote access information systems is aimed at expanding research opportunities for searching and online work with digitized historical documents, as well as popularization of the archival heritage of the regions of the Russian Federation.

Abstract: The authors assess how 1897 Census papers stored in Russian and foreign archives are represented and preserved. The study of primary data document collections leads to a conclusion that the term “census papers” is heterogeneous and includes several different forms used depending on a type of household and region as well as first, second and third copies of census forms. A peculiar feature of the article is the presentation of conclusions in the form of cartograms based on modern and historical maps. The study has used source studies analysis and spatial analysis as well as a complex approach treating census papers as a unified historical source irrespective of their storage place. The research novelty is identification and introduction of a complex of nominative 1897 Census data. In addition, the authors propose an original approach that takes into account both the number of areas populated and the number of census papers preserved in them which allowed them to assess the degree of preservation of census materials in Russian Empire uezds. The article concludes that census papers with different preservation state have been identified for 47 % of guberniyas and 25.5% of uezds.  Census paper collections cover regions of European Russia and Siberia, partly those of the Caucasus and Central Asia. The volume of census paper data preserved and their "territorial spread" allows one to consider them a complex source on the history of the Russian Empire population at the turn of the 19th century.
