All numbers are the annual average of our five-year projections.


Total Usage

The projected Usage of the journal by your institution.  Usage is a measure of the journal's value to your institution.  It is calculated as:

Usage of a journal = Downloads from the journal
                + (Citations to the journal by your authors) * (citation weight)
                + (Authored papers in the journal) * (authorship weight)


Downloads

The number of times people in your institution will download papers from this journal.  We base this on your COUNTER statistics and literature on download decay curves (how often an article is to be downloaded based on how long ago it was published).


Citations to papers

The number of papers in this journal that have at least one author from your institution.  This number is based on the authorship patterns of the previous five years.  The importance of this number to overall Usage is determined by the Authorship Weight setting.
