This is an ongoing informal survey of open access policies in the gallery, library, archive and museum (GLAM) sector. It examines how GLAMs make data – whether digital objects, metadata or text – available for re-use. The survey is intended to be a starting point for people who want to find and use open collections or data. It may also serve as a resource for GLAMs exploring open access data and policy development. Survey results are shared in this regularly updated spreadsheet. This download on Internet Archive is a backup snapshot of the spreadsheet on April 30, 2020.
