What is “correct”?

I was thinking about the library as a place of accessibility and symbol of “leveling the playing field”. After reading the piece, Queering the Catalog, I had second thoughts. When I think about the future library as an institution, I wonder how people in power are attempting to change the organization, labeling, and categorization of books and information. When it comes to the idea of correctness, how do we know that the decisions being made are correct? To some extent can we question the idea of bias, where everything is subjective to the individual? How can we argue that the library will become a place of correctness when we don’t even know what correct is? When we think of the library as a place that should be a sanctuary of information for all patrons that enter, how far will changing the library change the landscape of information and interpretation?
