This paper presents methods to develop metrics that compare Big Deal journal packages and the journals within those packages. Deal-level metrics guide selection of a Big Deal for termination. Journal-level metrics guide selection of individual subscriptions from journals previously provided by a terminated deal.The paper argues that, while the proposed metrics provide helpful quantitative data for comparative analysis, selection of individual subscriptions must also involve informed judgment about alibrary's subject coverage needs and alternative sources of access. The paper also discusses how replacing a Big Deal with a reduced number of individual subscriptions may affect the collections budget, use of other resources, and interlibrary loan.
