The Coronavirus Open Citations Dataset curated by OpenCitations currently contains (as of 20 April 2020) information about 124,295 citations and about the 42,213 citing or cited articles involved in these citations. A subset of these data (stored in the "_partial.json" files introduced below) is used for creating the visualization available at https://opencitations.github.io/coronavirus/. Each item in both the JSON files storing citations ('citations_full.json' and 'citations_partial.json') contains the following fields: "id", a numeric identifier of the citation; "source", the citing entity; "target", the cited entity. Each item in both the JSON files storing article metadata ('metadata_full.json' and 'metadata_partial.json') contains the following fields: "id", the DOI of the article; "author", the surname of all the authors of the article; "year", the year of publication; "title", the title of the article; "source_title", the title of the venue where the article has been published. In addition, any item in the file 'metadata_partial.json' contains another field: "count": the overall number of citations that the article received.

This version fixes a missing article title in the partial data used for visualization purposes.
