The problems of design and implementation of the electronic archive of documents are considered in the paper. The project intended to create a Webversion of the archive consisting of different paper documents. Functionals implemented in the system supply operators-archivists with easy-to-use tools to insert and update information, and provide convenient and transparent interfaces allowing end-users to visualise and search for information stored in the archive. The system consists of separate modules; most of them are implemented in the three-level client-server architecture. The system has been successfully applied to the creation of the Web-version of the unique collection of the documents that remained after the premature death of academician A.P. Ershov, one of the leading Russian computer scientists. This electronic archive is now available at http://ershov.ras.ru.
