Digitizing old physical newspapers, including content discussing various scientific fields, makes it easier to find articles from various periods and enables access to a significant quantity of varied studies, opinions that would otherwise prove difficult to track down in hard copy. Do newspaper articles objectively reflect, or accurately depict, ongoing dialogs in a given scientific field? If a certain scientific opinion is continually represented by a number of articles in a number of different media outlets, this gives the general public the impression that there is a consensus in that scientific community. When mainstream scientific views change, then popular news articles expressing these newly established opinions prevail. Typically, opinions that run contrary to the dominant narrative are rarely ever published in popular newspapers and magazines. However, this omission of alternative views is not due to alternative perspectives not existing. The numerous articles on rapid climate change and global warming written in the last three decades are a good example to take note of. Unlike today, half a century ago the majority of meteorological articles and studies were focused on the topic of global cooling. The authors of these newspaper and magazine articles were likely not climate experts, but journalists who merely conveyed the opinions of meteorologists and climatologists.

In this paper we present digitized works of Dimitrije Danić (1862-1932), first Serbian doctor of science in the area of mathematics and a prominent professor of the Military Academy in Belgrade. Digital copies of his monographs and text-books are deposited in the Virtual Library of the faculty of Mathematics in Belgrade. These works were digitized in the frame of the longlasting digitization project Digitization of scientific and cultural heritage, run by the Mathematical institute in Belgrade and the Faculty of Mathematics in Belgrade.

The Pedagogical Museum in Belgrade has been working on the digitization of its funds for many years. Bearing in mind the importance of digital copies, this year, a workplace called Operator of digital technology was established. In the coming period we will be able to procure equipment and adequate programs which will be provided the merging of all digitized funds, archival materials, photographs and books to date.Last year, 2018, the Ministry of Culture and Information of the Republic of Serbia passed the Rulebook on closer conditions for the digitization of cultural heritage which defines closer conditions, tasks, duty, standards and processes of digitization of movable and immovable and movable cultural heritage and property which had previous protection. To achieve this goal, the Pedagogical Museum decided to digitize, among other documents, the Diary of Lazar Jovancic, who led him in the Italian captivity during the Second World War. We believe the digitized materials obtained from writings old more than 75 years, will be useful for historical research and clarification of some invents happened in the Second World War.
Lazar Jovancic led the diary from June 1941 to November 1943. In fact, his diary consists of his letters addressed to his wife BosiljkaBosaValic-Jovancic who spent the Second World War in Belgrade. Lazar was captured around Debra and sent to a camp for officers located in the north of Italy, in Corto Maggiore in the province of Piacenza, the province of Lombardy. Life in the camp was not easy. Prisoners were scarce in food, during the winter they did not have heating, they were often ill, and communication with Serbia was hampered. For Lazar the most difficult was his constant concern for the survival of his wife.

It is generally considered that Jovan Karamata is one of the greatest and the most influential Serbian mathematicians in the XX century. His mathematical contributions belong mainly to mathematical analysis, particularly to the Tauberian theory. Probably his most known and most important work is his invention of slowly varying functions. Today, this theory has many applications, particularly in probability theory, but in ordinary differential equations, complex analysis, number theory and even in cosmology as well. In this paper we present a digital collection ofhis books deposited in the Virtual Library of the Faculty of mathematics in Belgrade.

The unrestrained progress of technology in the first decades of the new millennium has led to changes that affect development in all areas of life, with consequences that affect our views and understanding of history, cultural heritage, and affect activities of museums too. The consequences of such changes are seen in the ways of collecting, storing, protecting, and displaying museum exhibits. The Virtual Time Machine is just one of the new approaches and applications of digitalization that has been applied to the Visitors’ and Memorial Books at the Museum of Yugoslavia. The narratives of the records left in the Visitors’ and Memorial Books, which in a way represent the reality and the various alternative visions of Yugoslav society until the end of the 20th century, are indisputably essential documents for the process of reification of reality that is characteristic of the Museum. The Virtual Time Machine is a link connecting the old and the new; it provided contemporary access to records within the project “Figures of Memory”. A digital collection of Memorial and Visitor’s Books was created, which made the content visible and accessible to the general public, which is of great importance for the “culture of remembrance in the Yugoslav context” (Đorgović 2019, 15).
