"The routing of law and legal materials at the Library of Congress presents unique challenges. How do law and legal materials end up in the Law Cataloguing Section for processing? In this presentation titled "Does this book go to law" Aaron Kuperman presents the issues that must be considered before determining whether or not to send an item to the Law Section for cataloging. Although the presentation does address some general principles for identifying law and legal materials, it was created primarily and intentionally for internal Library of Congress staff training." The site provides access to the 55 minute webcast as well as a transcript of the presentation.
