The exhibition entitled “Ivan Djaja: Life and Works” is the second virtual exhibition of the cycle “They Built Serbia” which is organized at the University Library “Svetozar Markovic”. The exhibition introduces us to the versatility of works of this renowned Serbian and world scientist. Through the texts, the chronology of life and works, a bibliography from the University Library collection, web bibliography, Wikipedia and citations we tried to present the complete personality of Professor Ivan Djaja. In the preparation phase of the exhibition all the materials were taken from the storage. The brochures which were in bad condition were bound and protected. Around ten publications were inserted into the e-catalog, and they are now processed and visible to users. A part of the rich University Library collection comprises dedications of Ivan Djaja to the people who were important for Serbian culture and science. The selected texts about some of Ivan Djaja’s works illustrate the depth of his interests which spread beyond the field he studied.
Djaja earned his PhD in 1909 after defending his thesis Etudes des ferments des Glucosides et des Hydrates de Carbone chez les Mollusques et chez les Crustacés (Study on ferments of glycosides and carbohydrates in mollusks and crustaceans) at the Sorbonne.
On March 6 1932, Ivan Djaja became a full member of the Serbian Royal Academy. Two scientific articles written by Djaja were published in the Voice of Serbian Royal Academy (Glas Srpske kraljevske akademije) in 1932. In the article entitled “Some features of the fight against cold” there is an augural address held at the annual ceremony of the Academy.
University Library “Svetozar Markovic”, according to the information from the bibliography, has a great number of works by Ivan Djaja, a scientist, professor, rector of the University of Belgrade and a writer. A number of his works has Ivan Djaja’s dedications to people who contributed to the development of culture in Serbia (Aleksandar Belic, Isidora Sekulic etc.)
The evaluation of the scientific work through the citation analysis represents one of the methods applied throughout the world and in our country. There are two reference institutions in Serbia (University Library “Svetozar Markovic” in Belgrade and Matica Srpska Library in Novi Sad) which make bibliographies of cited works according to the data bases Science Citation Index and ISI Web of Science (WOS) which are financed by the Ministry of Education, Science and Technological Development of the Republic of Serbia.
Wikipedia is a free-access, free content Internet encyclopedia in English founded on January 15 2001. Since the beginning of 2015 Wikipedia exists in 287 languages. Since 2003 there is also Serbian version of the encyclopedia with more than 310.000 articles which cover a great number of themes.
Ivan Djaja, as a renowned scientist, made effort to popularize science whenever he could. We present some parts of texts from the rich collection of the University Library in the category of popular literature.
“Naturalists are not usually prone to meditation. … Once in a while among them someone appears who helps the interest and ability to look into the base of transient phenomena which remain the object of study in natural sciences. … Hence the need in their work to set up a transition of a kind between the essence and phenomena. In that way they are similar to philosophers.” (Ksenija Atanasijević, Reflections of a Philosopher, Ivan Djaja “Downstream”)
