LINQ: The Librarians' Inquiry Forum is a practitioner inquiry model for public librarian professional development whose theoretical foundations are based in New Literacy Studies, Critical Race Theory and social epistemology. This research explains the development of the LINQ methodology and design across four public librarian communities of practices situated in geoculturally-specific locations. Data from the librarian inquiry groups collaboratively researching their professional practice is illustrated to convey how the LINQ model's critical race theory lens is applied to expose geocultural barriers endemic in the library and information science (LIS) field. One dataset is analyzed and discussed to substantiate a common thread through the four inquiry groups over time: that when public librarians work collectively to ask critical questions about their practice, such questions learned, serve to center local cultural values that are geographically specific and unique, redefining what it means to be a public librarian in geoculturally specific contexts.
