Abstract: The article discusses the experience of online publication of the scribe book of the Tver half of the Bezhetskaya Pyatina of the Novgorod land in 1545 on the NextGIS Web platform. The scribe's Book of 1545 is the most complete source describing the territory of the Tver half of the Bezhetskaya Pyatina of the XVI century. The book reflects the composition of landowners not only of the XVI century, but also of the period of independence of Veliky Novgorod. The paper describes methods of working with the geographical information of the book, creating geodata based on it and ways of presenting them in a web format. Attention is paid to various technical solutions, their strengths and weaknesses are considered. В The novelty of the research lies in a new look at the auxiliary element of the NextGIS Web web map, which is the Description displayed on the functional panel of its interface. The proposed approach turns the interactive geographical pointer accompanying the map into a platform for full-text publication of the source, in which the map performs the function of a container, always ready to display exactly the spatial context in which the geographical object selected by the user exists from the text of the historical source of the source. The main conclusion of the work is the conclusion that the proposed method allows you to combine the transmission of the main elements of the paper publication of the source with the advantages of a modern digital format, expanded due to the cartographic component.
