The best place to start is the International Campaign to Ban Landmines, which has lots of information including a brief history of landmines, a copy of the treaty and a list of states that have ratified it.

Landmine Monitor, the ICBL's research and monitoring arm, produces a yearly report with details of which countries and groups are still using mines, progress in mine clearance and information on casualties. See the 2009 report.

Human Rights Watch has numerous documents on landmines as well as a special microsite dedicated to the campaign to ban cluster munitions.

Mines Action Canada is a bilingual English/French site with concise fact sheets on issues like cluster bombs.

Handicap International has an informative site with a good media section offering videos, pictures and press contacts.

Norwegian People's Aid has information on its work in clearing landmines in post conflict zones around the world.

The International Committee of the Red Cross also has a useful section on landmines.

The Cluster Munition Coalition (CMC), an international coalition working to protect civilians from the effects of cluster munitions, is the best place to start for information on the campaign to ban them.

It has information on the new treaty and a list of countries that has signed. There are also first hand accounts from cluster bomb victims and an interactive map showing countries that produce, use and stockpile the weapons and those countries affected by them.
