[field "issue"] the issue sequence identifier (e.g. a number) to which the entity belongs; 

[field "page"] the page range of the resource described in the row; 

[field "type"] the type of resource described in the row; 

[field "publisher"] the entity responsible for making the resource available; 

[field "editor"] the editors of the document.

This version of the dataset contains:

129,436,832 bibliographic entities

389,069,283 authors, 2,862,406 editors, and 106,791,171 publishers (counted by their roles, without disambiguating individual entities)
