Three types of interviews were conducted for this study, most of them between May 2004 and August 2008, with actors from Brazil, Canada, Chile, Mexico, Peru, the United States, and Uruguay (see Table A1). Structured interviews using a social network questionnaire were done with informants from 123 civil society organizations (CSOs) from Brazil, Chile, Mexico, and the United States (listed in Tables A2 through A5). Semistructured and in-depth interviews were held with other civil society informants, government officials, parliamentarians, legislative staff, and international organization officials. Their names, affiliation, and the date and place of the interview are listed in Table A6, with the exception of interviewees that requested anonimity.

In many cases, more than one person from the same CSO was interviewed to answer the social network questionnaire. In other cases, individuals were interviewed more than once, and, sometimes, the same individuals were interviewed in more than one organization, as they switched jobs over the years. That is why the total number of questionnaires is different from the number of individuals interviewed in Table A1. The number of semistructured and in-depth interviews with CSOs is also different from the total number of interviews, which includes those undertaken with government officials, parliamentarians, legislative staff, and international organization officials (listed in Table A6).
