With the increasingly strong demand of scholars for the application of digital resources, the demand for digital humanities librarians in the job market is also on the rise. To determine the core competencies and skills required for digital humanities librarians, authors adopt a set of recent job announcements from the American Library Association JobLIST, and use both quantitative and qualitative analysis methods to conduct an in-depth descriptive and inferential analysis to seek the current core professional competencies required for digital librarians. The results indicate that professional foundation and higher degree are the key elements to become a digital humanities librarian, and technical knowledge and related skills are the most important needs of major libraries.
