This volume brings together most of the presentations made at the 40th International Conference of the Round Table on Archives (CITRA) held in Quebec City, 11-17 November 2007 on the theme "Cooperate to preserve diversity".
On the basis of an ambitious experience - the merging of National Libraries and Archives of Canada and Québec - three complementary perspectives were adopted:
- terms and conditions for the success of cooperation between archives, libraries and museums
- necessity - which is specifically related to archives - of close cooperation with the creators of documents in the electronic era
- association of the archives with two major international and regional digital projects currently underway.
