In the conditions of rapidly developing information society in Russia, the problem of ensuring children’s media security is becoming more urgent. Low-quality children’s literature (media products) is sold, distributed on the Internet, is in public and family libraries. Russian children currently are not protected from the influence of content that can have a re-socializing effect and promote destructive behaviour models. When choosing an interesting and useful book, children may be influenced by suggestions that are destructive to the personality of young reader. The authors substantiate the expediency of introducing the concept of “media security of childrenʼs reading” into the theory and practice of reading activity, both in relation to books and media products in general. The authors propose to solve the problem of the potentially possible re-socializing impact of some works of modern childrenʼs literature (media products) through the introduction of socio-cultural projects within the framework of information and recommendation support. At the same time, such support should include the creation of recommendation information and library products posted on the official websites of childrenʼs libraries and their online communities in the media environment, as well as the organization of their provision to users.The paper presents the results of library and pedagogical experiment, during which the socio-cultural project was developed, realized and implemented in the Pushkin Central Municipal Library of Kirov and tested in the parent community of younger schoolchildren, aimed at including the media security model proposed by the authors in the information and recommendation support for childrenʼs reading. The results obtained of project implementation indicate the effectiveness of the developed socio-cultural project, which is able to prevent the negative impact of low-quality literature.
