Information Literacy can be an enabler of social justice, as is reflected in core statements about information literacy, such as in the UNESCO-supported Prague Declaration "Information Literacy, in conjunction with access to essential information and effective use of information and communication technologies, plays a leading role in reducing the inequities within and among countries and peoples, and in promoting tolerance and mutual understanding through information use in multicultural and multilingual contexts."
The International Federation of Library Associations and Institutions (IFLA) has produced a blog post Social Justice: a Core Library Mission. The blog post also alludes to the value of information literacy "The skills to make this access [to information] meaningful are also important. Yet it is often those who struggle with the costs of information that also lack the knowledge or confidence needed to apply it. This holds them back from taking better decisions and improving their lives." https://blogs.ifla.org/lpa/2018/02/20/social-justice-a-core-library-mission/
