Imagine: the Library of Congress Classification and the Dewey Decimal System fall overboard and are lost at sea! What would a replacement for them look like? Let's explore that together, as we imagine a new system that leaves the problematic elements of our current systems behind. Macro-level taxonomy decisions cannot be made by any one individual, nor can they be made in a vacuum. In this collaborative session, members from all library departments will be invited to begin the work of identifying and discussing precisely what the problems are and brainstorming what possible solutions could look like.
