“Providing the users the most accurate information” has been the basic goal of libraries. It has also been the responsibilities of librarians. In order to be a good information provider, a library has to know the users’ information seeking behavior and to understand their seeking motivations, processes, and results. Many library and information science scholars paid attention to users of different background as their research subjects, but there were very few researches that focus on handicapped users. Therefore, when facing these users, many libraries, with little understandings on their information seeking needs, usually fail to give handicapped users proper assistance. In this kind of situation, these users have again become a weak group in the libraries. The blind library users are even weaker among them all. Traditional information circulation is by books or paper print; this frustrates blind people when acquiring information. Since libraries have the responsibilities for information dissemination and social education, they have to understand and satisfy the needs of all users. Sufficient researches and theses are initial and very necessary for a good understand about the certain group of users. This paper focuses on the blind library users and their information seeking behaviors. The research methods are mainly by visiting and interviewing. Through interviewing the blind users, the author learned to know their needs, sources, references, and application of information. The author’s purpose is to do experimental study and then offer suggestions on library service for the blind.
