Creating New Information and Communication Models in Working with Users within the Google Library Project
Authors: Savitskaya Tatiana E. 
Published: August 2020

The article analyzes characteristic features and development logic of the library project by Google, which started from the famous Google Book Search project (also known as Google Books and Google Print), and later as Google Play Books within the multi-platform multimedia service Google Play. For decades, a constant trend of the corporation’s activity has been the development and testing of new social and communication models in working with users, combining the complexity and global reach of the audience with the use of its interactive potential. In the early 2000s, the company initiated mass scanning of library collections, thus starting the development of a new institutional paradigm for electronic libraries. Later, having developed new business models for the distribution of electronic copies of printed products in the course of numerous legal proceedings on charges of copyright infringement, it also pioneered the new information market development.From the very beginning, Google Book Search was aimed at the mass user, which was facilitated by its constantly expanding set of options and increasing level of comfort of access to the resource. In 2006—2010, the service presented an opportunity for users to download, in pdf format, books free of copyright law; a new viewing interface “About this book” was added; an opportunity to operate texts using “My library” option was provided; a mobile version of the service was launched; access to statistical information on diachronic frequency dynamics of word usage based on the collected database was provided.The article analyzes the further development of the library project within the Google Play Books service, which allows users to read, buy and sell e-books, use bookmarks, download their own books in pdf and EPUB formats, and synchronize data on all user’s devices. There is assessed the social significance of the project in the context of the global electronic civilization development.
Ego-­documents as sources for the history of Belarusian national movement in interwar western Belarus
Authors: Gorny A. S. 
Published: August 2020

The main theoretical approaches that exist in domestic and foreign historiography on the problem of ego­docu­ ments are given in the introduction. Role of the Dutch historian Jacques Presser in creation of this term and its use in foreign historical science in the 1980–1990s is analyzed. The author of the article, taking into account European experience, is trying to give his own definition of the term “ego­documents”, adapted to Belarusian historiography. The author also notes the scientific feasibility of the active use of ego­documents when studying the history of the Belarusian national movement in the interwar Western Belarus.The main part of the article reveals the scientific value of ego­documents as sources for studying various topics related to the history of the Belarusian national movement in the interwar Western Belarus. As an example, the author took letters to the Vilnius Belarusian bookstore, and analyzed the scientific potential of business correspondence as part of epistolary sources. Five types of memoir literature, which help to expand knowledge about various figures of the Belarusian movement in the interwar Western Belarus, were formed. An analysis of university autobiography and curriculum vitae emphasizes the lack of knowledge of this type of ego­documents and its scientific value in the study of relations between Belarusian activists and the Polish state.In conclusion, conclusions are drawn about the insignificant use of ego­documents in the study of the history of Bela­ rusian nationalism in the interwar Western Belarus. The anthropological turn in historiography has determined the desire of modern historians to pay attention to the everyday problem of the Belarusian movement, its local features that determines the active use of ego­documents as sources.

Characters of Vulnerability of Girls to Commercial Sexual Exploitation of Children (CSEC): Case Studies in Lombok and Jakarta
Authors: Wicaksono Bagus Yaugo 
Published: August 2020

<div>The victims of commercial sexual exploitation of children (CSEC) -especially girls- both in Jakarta - and Lombok area are having unique characteristic of vulnerability, therefore in order to optimize supporting the victims, an understanding of these characteristics of vulnerability in both areas are required. The purpose of this article is to describe and analyze the implementation of Down to Zero Project conducted by Plan International Indonesia (PII) in North Jakarta, East Jakarta, West Lombok, and Central Lombok. By conducting desk review of documents and results of previous studies during the implementation of this project, this study argues that; first, on the one side, the vulnerability of CSEC victims in Lombok areas tends to have a relation with poverty, furthermore the strict norms and value of custom could be challenging. On the other side, ineffective protection from family or caregiver makes a huge challenge for CSEC victims in the Jakarta area, in addition a heterogenous society and individualist characters create ineffective social protection for them. Secondly, these differences showed that the existing child protection system for girl victims of CSEC is not fully able to support them to reach the quality of life.</div><p> </p>
