The Internet has been the catalyst for the convergence of many subject areas and online platforms. Information professionals such as Archivists, IT developers and especially Librarians have been impacted in the development and promotion of digital humanities content for research, teaching, and learning in the modern academic library. In this case study, relevant findings from research that sought to determine the level of awareness of digital humanities in Irish Libraries is examined. The research project, "The Mary Martin Diary," is highlighted as an example of a multidisciplinary collaboration project that utilized library communication skills, project management skills, digital humanities tools and techniques, as well as other online resources in its development. These skills and tools have the potential to be applied to similar projects that librarians engage in. Recommendations derived from this research highlight the practical application of skills for information professionals and their roles in the development and promotion of digital humanities content for research, teaching, and learning in the modern academic library.
