As knowledge brokers, librarians are living in interesting times for themselves and libraries. It causes them to wonder sometimes if the traditional tools like the Dewey Decimal Classification (DDC) system can cope with the onslaught of information. The categories provided do not always seem adequate for the knowledge-discovery habits of today's patrons. They have grown accustomed to new ways for their information needs to be met, from the fire-and-forget style of a hard-to-control classic Google search to the pervasive, always-on style of Google Now. As librarians see the need to provide unique and cutting-edge knowledge discovery to their users, the author argues that the DDC can play a key role in fulfilling this purpose, by thinking about how Dewey can help solve today's problems, rather than applying and displaying numbers in the same way we have always done. From the very beginning, for a variety of good reasons, usage of Dewey was focused on the numbers as identifiers. The Dewey number is an iconic, ingenious shorthand for a subject category, transforming a physical space into an intellectual one. But to reap any benefits from this transformation, the categories must be communicated to the patron in different ways, not just as bare Dewey numbers. Dewey is a community resource that is dependent on user input to stay relevant. Librarians have access to new communities of tools like WebDewey, Dewey blog, and even Twitter for collaboration. The DDC is a living and breathing organism that can change every day.
