A modified index of journal standing in a stratified journal to journal citation network is proposed. The original index, generated through an application of input-output analysis, is used as the first step of an iterative procedure that converges on the new index. This index, an eiginvector of the inverted matrix used in the input-output analysis, has improved validity and better distributional properties than the original index.
The concept of a stratified journal network is advanced where the nodes are journals and the relation is citation aggregated over the articles in these journals. The standing of the journals in the network can be measured through tools based on input-output models. These measures can be used to chart the changing status of journals at different time points.
