NDSA:Discussions on Preservation Storage Topics

Statement of Purpose

The Infrastructure Working Group, in February 2012, initiated a series of open conversations on detailed aspects of preservation storage. These conversations are conducted over the listserv and each topic is discussed over the course of 2-3 weeks. A list of future, potential discussion topics is maintained at bottom and can be augmented by group members. This page serves to capture the content of those conversations for further elaboration by group members.
