The Prepublication Data Service is a free service offered by the National Library of Australia. This service is for Australian publishers and self-publishing authors who want the details of their upcoming publications made available to Australian libraries, library suppliers, and other members of the book industry for acquisition purposes. Why should I use the Prepublication Data Service? Information about your upcoming publication will be made available to libraries and library suppliers around Australia via Libraries Australia and Trove, creating greater exposure for your book, and increasing the potential for book sales. Am I legally required to use the Prepublication Data Service?
