NLM reported at the Spring 2001 CNI Task Force Meeting on the permanence levels it has developed to communicate to users which of its Web resources will be kept available permanently. Since that time, NLM has implemented the system and created an archive for resources that are outdated or superseded but of permanent value. The archive is a separate but integral part of NLM’s main Web site. This presentation will describe the system in place for assigning permanence levels, the structure of the archive, the archiving process, and features developed for navigating within the archive and between the archive and the current site.
