The data collected is based on the responses of fifty authors/researchers, who have presented full-text papers published in the International Conference Series on Grey Literature. The dataset consists of ten questions, three of which are open-ended. The data contains the number and percentages of responses to questions dealing with the author’s own empirical research data, its current availability, and the author’s willingness to archive the data and make it openly accessible. The data in this study was collected and computer analyzed via Survey Monkey, where it remains stored along with a copy in Excel housed in the DANS Easy Archive. The data from the study was collected in 2011 within the framework of an enhanced publications project². Since then, emphasis on data preservation, open access, and the reuse of data has increased exponentially. This data from six years ago offers a valuable baseline that would allow for a follow-up questionnaire in part or whole. Hereby, one would stand to gain insight into changing attitudes and practices within GreyNet’s research community and renders potential (re)use by other professional research communities.
