References are employed in most academic research papers to give credits and to reflect scholarliness. With the upsurge in academic publications in recent decades, we are curious to know how the number of references cited per research article has changed across different disciplines over that time. The results of our study showed significant linear growth in reference density in eight disciplinary categories between 1980 and 2019 indexed in Web of Science. It appears that reference saturation is not yet in sight. Overall, the general increase in the number of publications and the advanced accessibility of the Internet and digitized documents may have promoted the growth in references in certain fields. However, the seemingly runaway tendency should be well appreciated and objectively assessed. We suggest that authors focus on their research itself rather than on political considerations during the process of writing, especially the selection of important references to cite.

Electronic theses and dissertations (ETDs) have been a recent addition to the library's online access system, or digital project. This chapter traces the history of dissertations, from their printed form and issuance in microform by various agencies. It examines the changes in textual content and its presentation from the pre-digital to digitized documents, and the relation to software developed for music and other fields. It then examines the evolution of audio and video formats for the accompanying materials, particularly in the performing arts, and the content of these materials. It concludes with issues in ETDs management and ensuring long-term access and preservation, such as digital quality and copyright.

Researchers in major Mexico City archives in the early 1970s had access to very few finding aids for historical documents and record sets. Since then, archivists and researchers have worked diligently to organize record sets and create catalogues for an untold number of documents. Since the early twenty-first century, researchers in the Archivo General de la Nación, the Archivo Histórico de la Ciudad de México, the Archivo Histórico del Arzobispado de México, the Archivo Histórico de la Secretaría de la Defensa Nacional, and the Archivo General de Notarías have been able to access databases, searchable PDF catalogues, and a small array of digital collections. Work toward inventorying and cataloguing record sets began long before the development of technologies available today. Typescript catalogues for record sets in the Archivo Histórico de la Ciudad de México date from the 1920s. Work on inventories, card catalogues, typescripts, and published catalogues for record sets in the Archivo General de la Nación and the Archivo Histórico de la Secretaría de la Defensa Nacional began during the 1930s and 1940s. Work on cataloguing the documents in the Archivo General de Notarías and the Archivo Histórico del Arzobispado de México began during the 1980s and 1990s. Since the early twenty-first century researchers have been able to access databases, searchable PDF catalogues, and a limited number of digitized documents for all these major archives. New technologies began to make digitization possible, and thus Mexican libraries, along with archives, began to digitize primary and secondary sources. Some of those projects involve digitizing microfilm; others involve digitizing complete record sets and printed books. Still others involve transcriptions of historical documents. While the scope and quality of those projects vary from institution to institution, all create heretofore unimaginable access to historical documents.

Modern libraries have considerable information resources. Digital copies of publications, including bibliographic ones, are an integral part of information resources. The author studies the activity of the Russian libraries of Federal level on creation of digital copies of bibliographic editions, basing on the own library holdings. There are three national libraries — the Russian State Library, the National Library of Russia and the Presidential Library named after B. Yeltsin. The purpose of the study is to analyse the array of digitized bibliographic publications and to identify the place of digital copies of bibliographic publications in the information resources of the national libraries. The author considers the content of the electronic catalogues of these libraries by entering the same type of request. The article presents the results of study of the volume and content of electronic catalogues, obtained by the method of bibliographic keyword search. The author analysed the array of digital copies of bibliographic publications on various parameters — chronological coverage of digitized documents; language features; terms of access to electronic documents. The author notes that the priority is now given to the digitization of publications in the national language. The article presents the types of access to digital copies of bibliographic publications from the user’s point of view. The author considers the statistical data on the availability of digital copies of bibliographic publications in the collections of electronic documents and the presence of special electronic collections. The emphasis is made on the study of open access to digitized documents. The study revealed that the volume of digital copies of bibliographic publications in the national libraries is very small for the implementation of their inherent scientific and educational function; the access to bibliographic information resources is mostly limited. The author concludes that the level of availability does not meet expectations of the user; and Russian libraries should develop their activities to expand open access to bibliographic information resources.

The paper draws attention to such an important historical aspect as the connection between foreign humanitarian activities in Soviet Russia and Ukraine during the famine of 1921-1923 and the participation of the people of the USSR in the Great Patriotic War. It is well known that during the famine of 1921-1923, a large number of foreign aid organizations functioned in Russia and Ukraine and provided food, treatment and clothing to several million starving children who were doomed to death without outside help. Some of these organizations opened orphanages on the territory of the RSFSR for homeless children and children left without parental care. Many of those men and women who went to war in 1941-1945 were saved during the famine by foreign organizations. Thanks to modern databases of digitized documents on the Great Patriotic War, it becomes possible to trace the military fate of these people. The paper, based on the materials of the Central Archive of the Ministry of Defense of the Russian Federation and the National Archive of Sweden, provides specific examples of the fate of participants in the Great Patriotic War, who were saved in 1922-1923 by the Red Cross organizations of Sweden and the Netherlands.

Digital library provides an excellent opportunity to widely disseminate our documentary heritages and greatly increases access to library collections of rare documents as well as current research literature. Indian digital library initiatives aim at producing a vast amount of digitized documents pertaining to different forms of recorded human knowledge, ranging from the rare manuscripts to current research literature. Digitized documents are made accessible in online information systems either through intranet or Internet channels. However, maintaining an Internet-based online digital library system has several problems such as availability of web server for 24X7 timeframe, robust broadband connectivity, efficient retrieval engine, ownership of digitized documents, etc. This chapter tries to address and document some of the prevailing social networking issues affecting Indian digital library initiatives, particularly the collaboration patterns among participating institutions as well as funding agencies. This chapter also tries to identify social relationships amongst the networked institutions in terms of nodes and ties. Nodes are the individual actors within the networks, and ties are the relationships between the actors. This chapter shows how social networks in the collaborative digital libraries play a critical role in determining the way problems are solved, organizations are run, and the degree to which individual projects succeed in achieving their goals. Digital Library of India (DLI) is the largest digitization initiative in India spreading across states of India and involving over ninety organizations to ensure several thousands of rare books written in Indian languages as well as non-Indian languages are accessible through Internet channel. This chapter critically appraises the formation of a formal social network in the DLI project embracing local memory institutions across the states of India as well as the funding agencies. Similarly, this chapter also critically analyses and elaborates another collaborative digital library initiative in India, namely, Traditional Knowledge Digital Library (TKDL).

An interest in the fate of ancestors influences the overall way we perceive the past, above all, how we understand history through their prism. The title fashion for genealogy is inextricably linked with technological development - quick access to historical sources published on the Internet. Provision of this type of service has become an important element of the global economy. Global genealogy websites have billions of user profiles, indexed and digitized documents in their databases. Genealogists around the world organize into groups, associations, to structure the process by which genealogical information is more accessible. Genealogical DNA tests are also becoming more and more popular - they help to go back much further in the family history than the preserved written sources allow. Genealogy is also a field of science that is increasingly present in traditional media as well as in scientific discourse - it is the subject of symposia, conferences and scientific publications both local and international. The Polish market of genealogy services is much smaller than the American market, but also consists of thriving organizations and commercial companies. One of them is Your Roots in Poland, which presents the entire range of this type of services offered in our country.

Abstract. A search and analysis of a large number of historical documents has made it possible: (i) to discover so-far unknown tsunamis that have hit the French coasts during the last centuries, and (ii) conversely, to disprove the tsunami nature of several events referred to in recent catalogues. This information has been structured into a database and also made available as a website (http://www.tsunamis.fr) that is accessible in French, English and Spanish. So far 60 genuine ("true") tsunamis have been described (with their dates, causes, oceans/seas, places observed, number of waves, flood and ebb distances, run-up, and intensities) and referenced against contemporary sources. Digitized documents are accessible online. In addition, so as to avoid confusion, tsunamis revealed as "false" or "doubtful" have been compiled into a second catalogue. Both the database and the website are updated annually corresponding to the state of knowledge, so as to take into account newly discovered historical references and the occurrence of new tsunamis on the coasts of France and many of its overseas territories: Guadeloupe, Martinique, French Guiana, New Caledonia, Réunion, and Mayotte.
