In December 1954 Novi Sad Agreement was signed. Matica hrvatska and Matica srpska published an orthography manual in 1960. Although widely praised by all levels of Serbian and Yugoslav party officials and intellectuals, the orthography was roundly criticized by Croatian intellectuals, who saw the work as too Serb-centric. Their criticisms stemmed mainly from an analysis of the case of larger differences between the two languages, claiming that the dictionary favored the eastern variant of the language over the Croatian. In 1960 Matica founded its Publishing Institute (Nakladni institut).
