Working Group to Investigate Use of CC BY to designate holders of public domain collections

CC Open Culture Platform Working Group 5 focused on analyzing the need for cultural heritage institutions (CHIs) to be credited for the digital reproduction of the material, even when the material is in the public domain, to attest the origin of digitization while informing every potential user about the institution of preservation. To respond to this need, CHIs mostly used CC BY attribution licenses to share the digital reproductions of their collections in the public domain instead of CC0 or PDM. Is it legally accurate and good practice with CC licenses and public domain tools to apply a CC license to material in the public domain using the attribution copyright clause to indicate information about CHIs? Is this practice a sign that CHIs need support to better use CC tools that can accomplish their need without interfering with the public domain? <a href="https://medium.com/creative-commons-we-like-to-share/report-of-the-working-group-to-investigate-use-of-cc-by-to-designate-holders-of-public-domain-679e75c05e8f">Click Here</a>
