To what extent does a corporate information unit impact upon the company in which it is based?

Purpose – The purpose of this paper is to discuss the extent to which the impact of the information unit (IU) is felt within the parent organisation. Design/methodology/approach – The paper opted for mixed methods approach combining two survey methods: a quantitative questionnaire with a follow-up set of qualitative interviews. Findings – The IU was felt to have an impact; however, the definition of impact was very difficult to pin down. There is a need to promote the work of the IU. Research limitations/implications – Because of the chosen research approach, the research results may not be replicable. Additionally, there is a risk of researcher bias. Practical implications – The paper could be used to help study impact in other special libraries. Originality/value – This paper seems to be unique in studying the impact of a corporate library using this approach. It will be of use to other corporate librarians and possibly those looking at mixed methods. [ABSTRACT FROM AUTHOR]
