Virtual reference in UK academic libraries : the virtual enquiry project 2008-2009
Source
Library review. 59(2010) no.1, S.40-55

Abstract
Purpose - The purpose of this paper is to present a snapshot of virtual reference services (the use of instant messaging or chat for enquiries) in UK academic libraries, and provide information about software for libraries considering providing a virtual reference service. Design/methodology/approach - The paper summarises the results of a 2008 UK-wide survey of academic libraries and gives a brief overview and comparison matrix of top virtual reference software products as tested by the Virtual Enquiry Project. Findings - Virtual reference services are not widespread in UK academic libraries. However, current service providers are planning to continue or expand services and a majority of academic libraries surveyed are considering starting a service. Originality/value - This is the first survey of its kind among UK academic libraries.
