Developments in ICTs and knowledge societies have revolutionized the traditional paradigms of education. There is a lot of emphasis on a culture of sharing and collaboration in the education scenario of today though educators have certain inhibitions about sharing of knowledge, ideas and resources. The present study was undertaken to explore the sharing behaviour of the faculty of the National Open University in India. Data was collected through a structured questionnaire on knowledge sharing behaviour and barriers to sharing from 62 faculty members belonging to various disciplines. The findings suggested that sharing was less preferred voluntarily and in networks; publishing was most preferred knowledge sharing mechanism; sharing of learning materials was more encouraged in the institution; and borrowing from Internet was more preferred. The important perceived barriers included lack of recognition and absence of organizational knowledge sharing culture. The findings have been discussed in relation to related research and the existing institutional context.
