The "Aligning National Approaches to Digital Preservation" (ANADP) conference was held at the National Library of Estonia, from May 23-25, 2011. More than 125 delegates from more than 20 countries were gathered in Tallinn, Estonia and explored how to create and sustain international collaborations to support the preservation of 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.
