The National Library Week, which proceeds in the virtual environment this year and has moved into its end, allows taking a closer look at how libraries as cultural institutions contribute to fostering progressive society and reducing digital and social divide. For more than a decade, libraries have been teaching citizens to use the internet and digital technologies and thus prepared people for outlasting the complicated circumstances of the quarantine: shopping online, using electronic services, communicating virtually, etc. Recent initiatives, which gained wide public attention, also show their significant contribution: during the quarantine, libraries voluntarily started to print protective face screens for medical professionals by using 3D printers (over 6500 such screens have been already printed) and offered to put at the provisional disposal of local authorities newly obtained computers for supplying the needs of schoolchildren involved in the process of remote learning.
