The problem of a user orientation in modern information resources is raised. The role of electronic guides as a means of multidimensional information search is noted. The authors of the article translate the previously proposed definition of the concept of “electronic bibliographic guide” and reveal its significant features as a polystructural phenomenon. The authors analyze electronic bibliographic guides presented on the websites of federal and central libraries of the subjects of the Russian Federation. Their multidimensional classification is proposed. It takes into account 19 division bases. The results of the proposed study of these resources are presented. The characteristics of electronic guides on the following features are given: the method of access to reflected objects; access mode; language; the breadth of thematic coverage; belonging to a certain field of knowledge; a storage medium; the presence of a printed analogue. The three-part structure of electronic guides is considered, including an introductory article, the main part and auxiliary pointers and/or a search bar. The results and key findings can be used to improve the creation of electronic guides and improve the quality of electronic information resources created in libraries.
