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access information systems is aimed at expanding research opportunities for searching and online work with digitized historical documents, as well as popularization of the archival heritage of the regions of the Russian Federation.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 article characterizes the goals and the structure of a database which aims at accumulating data of the First  General 1897 Population Census of the Russian Empire preserved by Russian and foreign archives. The database has two basic data input and data retention modules “Archive” and “Finding Aid”. The first module realizes the idea about the hierarchical level structure preservation characteristic of archival storage system (archive – fund – series – file – document). The second module reflects the search history that is data on archival reference books, information about electronic copies of archival reference books and documents as well as their access conditions. The interarchive database is a result of archive, document and source analysis both of archival fund documents and their finding aid. The author considers the idea to create such a system based on the First General Population Census of the Russian Empire new for Russian historical studies. A user is provided with an opportunity to carry out a search (online as well) by archives, funds, files, document types as well as administrative units with account of both to historical and present day names.
