The first part of this series is the monograph entitled ”Astronomska opservatorija u Beogradu o d 1956 do 1975. go dine” published in June 2010 in ”Publikacije Astronomske opservatorije u Beogradu”, Vol. 87. Afterwards the author studied and treated the p erio d b etween 1924 and 1955, somewhat longer and requiring more care, also published in ”Publikacije Astronomske opservatorije u Beogradu” in late 2014, Vol. 93. After these two p erio ds the more recent one, between 1976 and 1990, shorter than the other two (15 years), was studied and converted into a text. In this way the history of the Astronomical Observatory in Belgrade is covered continuously, year after year, during the 67 years of its existence.
