<p>This study is an exploration of how isolated special librarians communicate with other professionals in the library field. It examines the means in which they connect with librarians for professional development and social reasons; the value they place on this interaction; and the barriers that hinder this communication. The qualitative study used semi-structured, in-depth interviews with a representative sample of seven special librarians in New Zealand. The specific population was professionals at special libraries with either a solo staff member or a very small staff. There were several common themes among the interviews. Most interviewees were members of at least one professional library association such as LIANZA, but were more likely to be active in groups that were targeted at their field or at special librarians. When faced with a need for information, advice, or collaboration, the librarians interviewed were most likely to call upon colleagues they had met or worked with in the past, rather than an organised network or purpose-created group. There were several barriers identified that kept librarians from communicating with others, being active in the library field, and engaging in professional development activities. These included lack of support from their managers, lack of support from professional associations, feelings of isolation, and personal responsibilities such as raising a family. The common concerns raised by the special librarians could be taken into consideration by professional associations, organisers of communication networks, and the librarians’ managers. For a clearer picture of special librarians’ communication habits, a quantitative survey could be conducted, with survey questions informed by the results of this study.</p>
