The Code4Lib Journal – Copyright and access restrictions–providing access to the digital collections of Leiden University Libraries with conditional access rights

"To provide access to the digitized collections without breaking any copyright laws, Leiden University Library built a copyright module for their Islandora-based repository. The project was not just about building a technical solution, but also addressed policy, metadata, and workflows. A fine-grained system of access rights was set up, distinguishing conditions based on metadata, IP address, authentication and user role."
