Professional catalogers in an academic library have professional responsibilities in librarianship, scholarship, and services to the library, institute, and professional organizations. However, whatever the catalogers do have to be in alignment with strategic directions of the academic library, and contribute to its institutional effectiveness. This presentation uses several projects from Georgia Tech Library as examples to illuminate the subject matter on the role cataloger in the 21st century academic library. It first discusses the role of cataloger in assisting the removal of print collections out of GT Library building and creating a seamless collection with Emory resources in EmTech Library Services Center (LSC). It then discusses the role of cataloger in cataloging and metadata management from the perspectives of resource discovery, data curation, repository services, eResearch archive, and digitization.
