PurposeThe purpose of this paper is to investigate the impacts of the COVID-19 pandemic on library and information services (LIS) and how library professionals overcome the challenges of COVID-19 pandemic in the current reality.Design/methodology/approachThis study used quantitative and qualitative methods to investigate the impact of COVID-19 pandemic on Bangladesh’s LIS professionals. A structured online questionnaire was designed for the purpose of a quantitative survey. The respondents of this study were LIS professionals in all categories of libraries (e.g. academic libraries, public libraries, special libraries and national library) in Bangladesh. A total of 106 responses from LIS professionals in Bangladesh were received. This study analyzed qualitative data using Braun and Clark’s technique for thematic coding. Researchers interviewed librarians in two phases (during the COVID-19 pandemic and after COVID-19) about how libraries cope up with the COVID crisis. The descriptive findings were examined using diverse descriptive statistics (i.e. frequency numbers and percentages), and for examining the significant differences among demographics’ information regarding challenges faced by LIS professionals, Mann–Whitney and Kruskal–Wallis tests were conducted. The qualitative responses were carefully analyzed for familiarizing, coding and theme generation.FindingsThe result showed that most LIS professionals (i.e. 46.2% and 43.4%) had faced difficulties in accessing e-resources from home and had failed to maintain balance between work and personal life and to offer remote library services. The LIS professionals mostly used Facebook Messenger and Zoom to communicate with their colleagues and users. Furthermore, many LIS professionals (50.0%) secured their health and safety, adopted hygienic procedures at their workstations and provided virtual reference services. The qualitative findings show that though some libraries have faced challenges in providing online sources and services due to the absence of authority interest, budget scarcity and inadequate information and communication technology infrastructure, some libraries took the initiative to establish library institutional repository and make it available for users from home.Research limitations/implicationsThe present study only concentrated on the staff and their actions during and after the pandemic, which was mentioned as a limitation. It would be more effective if the study also considered the user’s viewpoint. The researchers hope that this study will help LIS professionals to support and provide digital and innovative service initiatives in their organization.Originality/valueTo the best of the authors’ knowledge, this is the first of its kind study in Bangladesh where the staff of all types of libraries expressed their views on the problems they faced during the COVID-19 pandemic and the steps they took recently to overcome them.
