The Collections Trust is a UK-based charity that promotes standards and best practices in collections management. This document summarizes a seminar presented by the Collections Trust on copyright issues affecting museums. It discusses how two museums, York Museums Trust and Derby Museum and Art Gallery, have adopted open content licensing strategies to share their digital collections online. Both cases demonstrate positive outcomes from increased access and visibility, though each museum has different policies around what content can be shared openly. The document concludes by advising museums to consider their mission and goals when developing an open content strategy.
