*The 25 most important papers is an analysis of records downloaded from the Web of Science. The analysis identifies the 25 most important authors, journals, and keywords in the dataset based on the number of occurrences and citation counts. A citation network of the provided records is created and used to identify the important papers according to their in-degree, total citation count, and page rank scores according to the procedure described in Knutas et al. (2015).
