    Abstract
    Examines the comparative value of full text access and journal subscription through a sampling of journal issues available online from the Information Access Corporation and in print at James Madison University in Virginia. Presents a model for assessing the value of full text online subscriptions which can be used to evaluate journal subscription, back file retention, document delivery options, index selection, and online access
