Although conversations about information literacy have grown substantially since the ACRL Competency Standards (2000) and the Framework for Information Literacy for Higher Education (2016) were introduced, a significant amount of fuzzy concept use remains concerning certain information literacy ideas. Sometimes this fuzziness is the result of intentional omission, because the Framework and other official documents seek to give as much latitude as possible for developing information literacy instruction relevant to particular communities. This demonstrates a healthy level of flexibility. Elsewhere, however, definitions of concepts circulate among librarians that are problematically inexplicit. In this essay I will discuss one such inexplicit concept—the “information ecosystem”—and offer considerations for how to understand information ecosystems that are local to theological and religious studies disciplines.
