Purpose -New social discovery systems have social-type Web 2.0 features that allow users to enhance the content of bibliographic records by adding their own tags, ratings, and reviews. One of the primary underlying principles of cataloguing is that catalogue records be designed with the user in mind, i.e. user convenience. The purpose of this paper is to explore the relationship between the principle of user convenience and social discovery systems. Design/methodology/approach -A review of the literature and codes of ethics of associations of information professions was undertaken to examine: the ethical dimensions of creating catalogue records to reflect user convenience, the relationship between culture and user convenience, and how social discovery tools can facilitate the creation of interactive and flexible catalogue records that reflect the culture(s) and needs of the library communities in which they exist. Findings -Social discovery systems can address the primary barriers to creating catalogue records that meet user convenience: determining and reflecting the needs and cultural warrant of the users, and maintaining the quality and integrity of the catalogue records. Practical implications -Social discovery systems can serve as a bridge between cataloguers' desire to create accurate catalogue records that conform to accepted cataloguing standards, and their ethical imperative to ensure that these records meet the needs of the clients. Originality/value -The findings of this study pave the way for further research into how user-contributed metadata allow clients to express their needs and cultural warrant and to interact with one another and library staff.
