Oral sources
In addition to using publicly available documentary sources, oral sources were contacted for this report based on their field knowledge of the situation of conflict in Colombia. Some sources who were interviewed chose to remain anonymous for security reasons. Sources were assessed for their background, publication history, reputability, current ground-level knowledge and experience, seriousness of their research, and recognition of their credentials by peers, the media, and international bodies. Oral sources are described in the bibliography in Annex 1: Bibliography.
