“The Library of Congress has announced a transition to online-only publication of its cataloging documentation. As titles that are in production are released, the Library’s Cataloging Distribution Service (CDS) will no longer print new editions of its subject headings, classification schedules and other cataloging publications. The Library will instead provide free downloadable PDF versions of these titles. For users desiring enhanced functionality, the Library’s two web-based subscription services, Cataloger’s Desktop and Classification Web, will continue as products from CDS…Beginning July 1, print publications that are currently sold through CDS will become available as free, downloadable PDF titles through the Library’s Acquisitions and Bibliographic Access Directorate website. Because all of the content cannot be made available simultaneously, the retrospective titles will be phased in over time as PDF files.”
