Each journal is assigned to one of 22 research fields. In ESI, a journal can be assigned to only one field.  Journals such as Science and Nature are categorized as multidisciplinary since they publish research in many different fields. As a result, papers published in these multidisciplinary journals are assigned to a field based on the representation of the cited journals. For example, if the majority of citations to a paper published in Science come from neuroscience journals and the majority of cited references in the paper are to neuroscience journals, the paper is then categorized as neuroscience.
