This report describes approaches to PID resolution, and sets out best practices to be followed as well as future work in the area and a survey of the practices of different disciplines.

The Rogue Scholar science blog archive is adding important functionality to existing science blogs. The first step after a blog has signed up with Rogue Scholar is archiving the content. This is not only needed for long-term preservation but also enables full-text search and DOI registration with meaningful metadata.

In 1998 Tim Berners-Lee coined the term cool URIs (1998), that is URIs that don’t change. We know that URLs referenced in the scholarly literature are often not cool, leading to link rot (Klein et al., 2014) and making it hard or impossible to find the referenced resource.
