James Hennelly writes: “If you have paid any attention to cataloging matters over the past three years, you might have heard rumblings about something called the 3R Project, which is having a large impact on RDA cataloging. Among the 3R Project’s goals was optimization of RDA for international use and in linked-data environments. The emphasis on these two areas is based on a vision for future cataloging that will require greater sharing of metadata for more efficient creation of records but still allow for local practices to better meet the needs of library users. In short, the post-3R RDA is for those who want to catalog locally but share globally.”
