In 2021, the joint USA, Canada and UK Cataloguing Ethics Steering Committee published the Cataloguing Code of Ethics. The document is a community response to clearly articulated needs for a code of ethics addressing the specific responsibilities of cataloguers and metadata managers engaged in creating, sharing, enriching, and preserving metadata in an increasingly global and technology dominated cataloguing ecosystem. The Code was created using the work of volunteers drawn from the cataloguing community of practice in the USA, Canada, and the UK but also from Australia, Mexico, and Israel. It is a concise practical tool for reviewing cataloguing policy and practice through an ethical lens and is intended for use by practitioners (regardless of where they are on their career journey and whether they work for the cultural and heritage sector or for the companies that sell systems, content, or metadata); standards developers; students; and educators. The ten statements of ethical principles embody a commitment to: understanding and meeting user needs; ensuring access to resources and metadata; promoting collaborative partnerships; critically applying standards; acknowledging bias; respecting the privacy and preferences of those who create and publish information resources; advocating for the value of cataloguing work and access to appropriate education and training to build a robust and sustainable workforce; promoting diversity, equity and inclusion; taking responsibility for decision-making and ensuring transparency in working practices. It is intended that the Code will provide agency and empowerment for cataloguers and metadata managers, both now and in the future, as they seek to deliver solutions to ethical dilemmas that are part and parcel of day-to-day cataloguing work. The session will include a short introduction to the Code followed by group work that will allow attendees to learn how to use the Code to devise practical solutions. Each of the ten statements will be examined under the broader topic headings of; audiences, tasks, and hurdles; collaboration; and education, jobs and advocacy. The presenters will provide practical examples of ethical issues applying to each principle and invite attendees to contribute their own experiences and questions. Feedback will be gathered and shared for mutual benefit. Paper presented at the CILIP Metadata and Discovery Group (MDG) Conference & UKCoR RDA Day (6th - 8th Sept 2023 at IET Austin Court, Birmingham).
