More and more journals, magazines, and other periodicals are becoming available in electronic versions on the Web. Not all journal are available in electronic form.
Many journals are still avilable only in paper.
Most e-journal articles are not free. Gelman has to pay a subscription fee in order for GW students and faculty to access particular e-journals. The Web has not evolved to the point where there is one, comprehensive source to search to find any and all e-journal articles on a specific topic. Search by the title of the journal. Entries for e-journals will include a link to the web site where you can retrieve articles.
