"Over the past fifteen years, librarians have increasingly looked to theory as a means to destablize normative discourses and practices with LIS, to engage in inclusive and non-authoritarian pedagogies, and to organize for social justice. "Critlib", short for "critical librarianship," is variously used to refer to a growing body of scholarship, an intellectual or activist movement within librarianship, an online community that occasionally organizes in-person meetings, and an informal Twitter discussion space active since 2014, identified by the #critlib hashtag. Critlib "aims to engage in discussion about critical perspectives on library practice" but it also seeks to bring 'socal justice principles into our work in libraries' (http://critlib.org/about/)." --Back cover.
