According to some authors, printing houses were deliberately established in remote churches and monasteries like in case of Mrkšina crkva printing house, Rujno Monastery printing house and Goražde printing house, to hide their activities from the Ottomans. Jerolim Zagurović and Vićenco Vuković were the last printers of printed srbulje. There was only one book printed in 1638 in Venice by Bartholomew Ginami, but that was only a reprint of psalter with book of hours published by Zagurović in 1569. At the beginning of the 19th century collectionaries from many different countries, including Vuk Karadžić, collected srbulje. In Montenegro and Herzegovina this task was performed by Vuk Popović (priest from Kotor) and Vuk Vrčević, on behalf of Vuk Karadžić. Vuk Popović received from Vuk Karadžić new liturgical books printed on Serbian language and exchanged them for srbulje. Three Vuks (Karadžić, Popović and Vrčević) with support of Russian scholars collected almost all remaining srbulje from Montenegro. Besides from Montenegro, Vuk Karadžić also received srbulje from Dalmatia, Zadar, Osijek, Sombor, etc... Every time he travelled to Serbia Karadžić would use the opportunity to visit monasteries and prepare lists of their old liturgical books. This activities were not always welcomed by the people in service of knjaz Miloš Obrenović in Kragujevac. The influence of Russian language liturgical books began back in 1726 when Russian graduate teachers from Kyiv Mohyla Academy arrived at Sremski Karlovci's newly-established Slavonic-Latin-Greek schools. Based on the monastic rules of Vikentije Jovanović (Metropolitan of Karlovci) liturgical books had to be written in Russian. At the beginning of 19th century srbulje became scarce so churches had to import and use Russian language liturgical books. During 1830s srbulje were replaced with books written in Russian language.
