There are now many different digital stewardship tools, services, specifications and related resources available. Some have been around for a years, others a brand new. I have identified those that I know about in this list. Included are tools and services that:
- Have a principle purpose to support the long-term preservation of or access to digital information
- Have an orientation toward practical implementation (no research projects, conceptual models, frameworks, policy guidance, etc.)
- Have a public URL that provides current information
- Appear to be currently functional, maintained and in broad use.
This is a work in progress, and I will be adding and refining information over time. Please pass on any suggestions for new items along with comments for revisions.
