  The present study aims to establish a valid method by which to apply the
theory of co-citations to Wikipedia article references and, subsequently, to
map these relationships between scientific papers. This theory, originally
applied to scientific literature, will be transferred to the digital
environment of collective knowledge generation. To this end, a dataset
containing Wikipedia references collected from Altmetric and Scopus' Journal
Metrics journals has been used. The articles have been categorized according to
the disciplines and specialties established in the All Science Journal
Classification (ASJC). They have also been grouped by journal of publication. A
set of articles in the Humanities, comprising 25 555 Wikipedia articles with 41
655 references to 32 245 resources, has been selected. Finally, a descriptive
statistical study has been conducted and co-citations have been mapped using
networks and indicators of degree and betweenness centrality.
