Core problem:

The presentation of inaccurate dates by content providers, or failure to update dates in the knowledge base by knowledge base developers, causes inaccurate results or failed links in the link resolver.

User impact:

Individuals may be told that a resource they seek is not available when it is (for example, if the file is not updated to reflect the most recent issues online) or that a resource is available when it is not (for example, if content has been removed but is still listed in a holdings list). In the former case, valid usage will decrease; in the latter, individuals will eventually shy away from using the resource if attempts to follow links to it regularly result in dead ends.


Content providers should provide accurate holdings files of coverage dates in a timely fashion; link resolver owners should ensure they are processing holdings files correctly and promptly.
