Information Technology is making a lot of changes in the library. Especially the library computerization made the business of librarians convenient and made an impact in outsourcing and job reduction. The number of library users is decreasing because they can find information easily in the internet instead of library. But librarians are suspended in traditional business; they are not carrying out new role in changed environment. So, their identity is shaken. If a job does not have their identity, the job can not but disappears. This paper wished to find the identity of librarians in digital environment. For research the author examined literatures about new role of librarians and compared with librarian's opinions. To collect librarian's opinions, the author took e-mail survey to librarians who are working more than 20 years at libraries. Questionnaire consists of open-ended question. As a result, librarians are feeling their professional rewarding in public service. But they do not have much opportunity to service as professional.
