The publication of the astronomical journal "Saturn" started in 1935 as a messenger of the Yugoslavian "Astronomical Society", founded in Belgrade a year before. This monthly periodical was conceived as a semiprofessional journal with many popular articles intended to astronomy lovers. At the same time the journal was planned to be useful to professional astronomers, surveyors, meteorologists and seismologists, because there were published also scientific articles. Popular and professional articles were separated into different sections, and there also was a section with short notes and news for people interested in astronomy. The members of the Editorial board were a general and academician Stevan Bošković, known for his very extensive geodetic measurements in Serbia in the first decade of XX century and his translation of the famous Tsinger's three volume book on astronomy, and Vojislav Grujić who was holding two doctoral dissertations in mathematics related to astronomy, obtained at Strasbourg University in 1933. Articles were published in Cyrillic and Latin, reflecting in this way both variants of Serbo-Croation. Slovenian authors published in Slovenian. Some of the leading Yugoslavian astronomers and physicists published there, e.g. Serbian Milutin Milanković, Croat Stjepan Mohorovičić and Slovenian Lavo Čermelj. The journal was published for the period of six year, 1935-1940. All 60 volumes were recently digitized and deposited in the Virtual Library of the Faculty of Mathematics in Belgrade. Volumes printed in the period 1935-1937 were digitized by Žarko Mijajlović and in the years 1938 and 1940 by Aleksandar Jovanović, an administrator of the Faculty of Mathematics. Digitization of this periodical for the year 1939 is done by the National Library of Serbia. We thank to Mrs Tamara Butigan and Mrs Jasna Majerle from the National Library for their help during the relization of this small project. We also thank to prof. Nadežda Pejović who actually initiated this project, for her support. (Ž.M.)
