The diploma thesis " Reading and Informing Habits of Users of the Ivan Goran Kovačić City Library During the COVID-19 Pandemic " investigates the extent to which users used library services in 2020 and 2021. During the pandemic, in 2020 and 2021, the library in Karlovac, like others in Croatia, faced challenges in business and communication with users. Quarantine and then epidemiological measures made the work of the library difficult. The introductory part of the paper explains the meaning and context of reading habits, the library, the COVID-19 pandemic, and one chapter reviews the Year of Reading. The key part of the diploma thesis is the research conducted using the interview method with the director and part of the staff of the City Library Ivan Goran Kovačić in Karlovac. The library's departments, publicity and attitude towards users during 2020 and 2021 were analyzed. The conclusions of the research are that the Karlovac City Library lost some of its users during the COVID-19 pandemic, but despite the reduction, members used the library's services more. The beginning of the pandemic was challenging for librarians and users, and in order to ensure the best possible epidemiological conditions, librarians from Karlovac organized a drive-in book loan system and a COVID quarantine for returned books. During 2020 and 2021, social networks proved to be a fast and simple channel for communicating with users. During the COVID-19 pandemic, despite the demanding working conditions, the library proved how it can get closer to its users.
