On May 23-25, more than 125 delegates from more than 20 countries gathered in Tallinn, Estonia, for the "Aligning National Approaches to Digital Preservation" conference. At the National Library of Estonia, this group explored how to create and sustain international collaborations to support the preservation of our digital cultural memory. This publication contains a collection of peer-reviewed essays that were developed by conference panels and attendees in the months following ANADP. Rather than simply chronicling the event, the volume intends to broaden and deepen its impact by reflecting on the ANADP presentations and conversations and establishing a set of starting points for building a greater alignment across digital preservation initiatives. Above all, it highlights the need for strategic international collaborations to support the preservation of our collective cultural memory.
