公共图书馆的社会责任包括图书馆自身行为所产生社会效果的责任和通过自己的活动积极影响社会问题的责任。由于受到某些因素的影响,公共图书馆的社会责任并没有得到充分的履行。本文首先对21世纪公共图书馆社会责任的内涵作出阐述,进而提出图书馆社会责任的实现方式。 The social responsibility of public libraries includes the responsibility of the social effects generated by the library’s own actions and the responsibility of positively influencing social issues through its own activities. Due to certain factors, the social responsibility of public libraries has not been fully fulfilled. This paper first expounds the connotation of social responsibility of public libraries in the 21st century, and then puts forward the ways to realize the social responsibility of libraries.
