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 a librarya€?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.
