NASIG's Core Competencies for Electronic Resources Librarians Revisited: An Analysis of Job Advertisement Trends, 2000-2012

During its relatively short existence, the electronic resources librarian has often shared responsibilities with other areas of librarianship. To highlight the uniqueness and provide a level of understanding about the position, the North American Serials Interest Group developed NASIG's Core Competencies for Electronic Resources Librarians based on a study which analyzed the occurrence of descriptors - responsibilities and qualifications - from job ads posted between 2005 and 2009. The aim of this article is to build on NASIG's Core Competencies by expanding the time period considered. Data from the additional years brings to light both rising and declining trends reflecting changes in electronic resources librarian responsibilities and requirements. The author contends that the findings reported in this article may be useful for refining NASIG's Core Competencies as the profession evolves.
