This document summarizes a presentation about the current state of college libraries and how disruptive innovation theory can help predict their future roles. It discusses how digital technologies and open access are disrupting traditional library collections and services. Specifically, it outlines how the shift from print to digital resources and from "just-in-case" to "just-in-time" collection development will significantly reduce the need for libraries to purchase extensive print collections. However, libraries can take on new roles curating special collections and providing services like research evaluation that the market cannot easily replace. The presentation aims to start a discussion about what new jobs libraries could perform and how to manage the disruption to traditional models and values.
