Purpose: The purpose of this paper is to discuss the results of a 2006 survey of UK Higher Education OPACs in order to provide a snapshot of cataloguing practices for e-books. Design/methodology/approach: The OPACs of 30 UK HE libraries were examined in July/August 2006 to determine which e-books were catalogued, and the level of cataloguing treatment e-books received. Interviews were conducted by e-mail with representatives of eight of these libraries. Findings: A total of 28 universities surveyed provided some OPAC records for e-books; most of these were for subscription collections from suppliers such as ebrary and netLibrary. Five universities included records in their OPACs for individual e-book titles from collections such as Eighteenth Century Collections Online (ECCO); four OPACs included records for free e-books. There are wide variations between institutions in terms of which e-books are selected for cataloguing. Research limitations/implications: The survey was undertaken at a particular point in time (summer 2006) and was not exhaustive of all UK HE OPACs. Practical implications: This research suggests that it should be made easier for users to search OPACs for e-books, and that libraries should provide more information on their websites about which e-books are catalogued. Originality/value: This paper addresses a gap in the UK literature on cataloguing e-books.
