The journals are Folklore, Journal of American Folklore, Western Folklore, and Journal of Folklore Research. The graph will cycle through each year from 1979-2013 and then repeat. Click on the pause button to stop the animation. If you mouse over a node, you will see what metadata that Web of Science provided for the citation appear below. If there is a DOI, there should be a working hyperlink as well. The year axis is a slider that you can adjust to go back and forth in time, though the graph is cumulative (it has to begin at 1979). Let me know if you find any errors. @joncgoodwin
