The present list of references was assembled during the period May 2007 -December 2010 in support of the work of the NEA Radioactive Waste Management Committee (RWMC) Project on Reversibility and Retrievability. It is not intended to update this list any further. Most of the cited references were downloadable from the internet as of December 2010. The reader should be aware however, that electronic availability may change with the progress of time. The list is provided to those who may want to undertake their own analysis. Although not exhaustive, the list will constitute for them a useful start.
