The Field Rankings table displays aggregate data for each of the 22 ESI research fields. For each field:

- The Number of Papers is the total number of papers in 10 years of Web of Science.
- The Number of Citations is the total number of citations received by all papers in the research field. The citing papers can be in any field.
- Citations per Paper is the total number of citations divided by the total number of papers.
- Highly Cited Papers is the number papers receiving the minimum number of
