Modelling the economics of interlending

Examines issues raised during a project, carried out by Coopers and Lybrand Associates on behalf of the British Library Document Supply Centre, which looked at interlibrary lending (ILL) costs and compiled an economic model of the ILL process. Discusses the calculation of existing costs as well as costs after hypothetical changes in ILL. Presents a data collection methodology and computer based model which should enable librarians to collect and analyse data for their own use whilst adding to the main database.
