This research provides librarians with a model for assessing and predicting which platforms patrons will use to access the same content, specifically comparing usage at the Ohio Library and Information Network (OhioLINK) Electronic Journal Center (EJC) and at Elsevier's ScienceDirect from 2007 to 2013. Findings show that in the earlier years, the EJC was frequented more than ScienceDirect, but, over time, users have gravitated to ScienceDirect over the EJC at a significantly higher rate. In addition, the data show that the higher use of ScienceDirect began prior to and only grew after a devastating platform failure of the EJC in 2009.
