Portals are thematic sections of the Encyclopedia of Nizhny Novgorod that gather the most significant materials on broad topics in one place. Each portal brings together articles related to a particular sphere of life in the city and region: Portal:People, Portal:Nature, Portal: Culture, Portal:Business), documents, and the everyday experience of Nizhny Novgorod residents. Portals are convenient for those who want a general overview of a topic without knowing in advance the titles of specific articles.
