Data from "Data Retention Status"

The ROR-ID became the initial criteria in determining the survey population in this study. Of the 223 organizations listed in the 4th edition of the International Directory of Organizations in Grey Literature (IDGL), 51 were selected based on their currentness and type(s) of affiliation with GreyNet International.

The closed-ended part of the questionnaire dealt with the types of data produced and/or collected in digital and non-digital formats. Also, it inquired as to whether the data was open access compliant or via paid subscriptions. If metadata was assigned, inquiry was made as to the content licensing, and if the organization provided internet online services.
