The Covid-19 pandemic affected various industries. Organizations are adapting to the new conditions so that their work with customers would not be hindered. Due to the COVID-19 pandemic, the work of libraries had to be changed and adapted to certain measures that were in force for public libraries. In addition to adjusting to these measures, they had to adjust to their users so that their relationship would not be disrupted. The purpose of the research in this paper is to gain insights into the available material on the Covid-19 pandemic in Croatian public libraries. Additional purpose is to raise readers' awareness of the availability of literature on Covid-19. The aim of the research is to determine whether and to what extent materials and information related to the Covid-19 pandemic are available in public libraries in Croatia, and what sub-topics are available in the literature on Covid-19? For this research, the method of catalog search of the public library fund will be used. Also, the content analysis will be used to analyze the material on Covid-19 available in the funds. The quantity of available material in each library, the share of the presence of individual works in the researched libraries will be determined and, after the available material is determined, it will be grouped according to subtopics related to Covid-19 (by categories: mental health, pandemic life advice , scientific literature, etc.) and the type of readers for whom it is intended (general population, scientists, children, etc.). The found material will also be grouped according to the author's country of origin, publisher, language and year of publication. Also, as many libraries will be included in reasearch, the research results will be compared among various libraries.
