Recently, many articles co-authored by librarians have been published in non-library and information science journals. This may indicate that embedded librarians are actively working as research partners in various fields. However, studies have rarely discussed the roles and experience of embedded librarians and, unlike the USA and European countries, the activities of embedded librarians in Korea are not well reported. This study collected and analysed co-authored articles from Korean faculty and librarians. In addition to identifying the role of the embedded librarian by analysing the author-contributions texts of the articles, the study examined the backgrounds of librarians and the difficulties of collaborating through interviews with librarian authors. The results of the analyses show that the number of collaborative articles by faculty and embedded librarians increased over the years and, of these, almost 70% were medical publications. The roles of the librarians outlined in the author-contributions texts were as reported in previous studies but, in many cases, their role was more significant than traditional liaison work, such as reporting the study’s methodology or approving the final draft. In the interviews, the embedded librarians expressed that they had experienced some difficulties, such as lack of time, insufficient guidelines and an inadequate curriculum in their library and information science department. For librarians to be recognized as research partners, they need to communicate well with team members and have knowledge, skills and abilities related to the research. Further, to achieve this collaboration, the curriculum of departments should be reformed. If such efforts are made, it is expected that embedded librarians will continue to excel in their role as liaison librarians, which has contributed to supporting research projects.
