Literature in the Croatian language created and printed in the sixties and seventies of the last century will be marked in many segments by ideological circumstances and postulates of the rule of communism at the time. Even then, literature written for children and young people will not bypass this influence of indoctrinated political order. The paper examines the historical framework of the Croatian cultural and social space from 1966 to 1974, in which the printed editions of the famous Croatian Library Vjeverica are located and chronologically analyzed. At the beginning of July 1966, there was a political coup in the then-Yugoslav regime (the famous Brijuni Plenum). Only a year later the Declaration on the position and name of the Croatian literary language was created. These two (political) events are taken as a starting point for observing new, more open, and more liberal approaches and views of culture, of which literature for children and young people was part. The period of these “freedoms” will last until the adoption of the new Yugoslav Constitution (1974) when there is a weakening of “freedoms, rights, and duties of (Croatian) man and citizen in the Yugoslav community” (cf. Mihaljević 2016: 5). The publishing series of the Library Vjeverica are observed and analyzed in the paper by the years of printing. The aim of the paper is to describe authors in one place, their national and regional affiliation, domestic and foreign titles, and languages in the translations of the Library Vjeverica through the observed (turbulent) sociopolitical (Yugoslav) cultural atmosphere and political time – from the Brijuni Plenum (1966) to the adoption of the new Constitution (1974).
