BibTeX：多个机构

Question

我引用了两家机构使用 BibTeX 在线联合发表的一份报告。我认为合适的条目类型应该是techreport。如果有多个机构，是否有标准的方法在 .bib 文件中输入机构名称？现在，我只是在字段中的两个机构名称之间添加一个“and” institution，如下例所示：

@techreport{coghlan2008mortality,
    author    = "Coghlan, Benjamin and Bemo, Valerie Nkamgang and Ngoy, Pascal and Stewart, Tony and Mulumba, Flavien and Lewis, Jennifer and Hardy, Colleen and Brennan, Richard",
    title     = "Mortality in the {Democratic Republic of Congo}: An ongoing crisis",
    institution = "International Rescue Committee and Bernet Institute",
    type     = "survey report", 
    year      = "2008",
    month    = "jan",
    note     = "\url{https://www.rescue.org/sites/default/files/document/661/2006-7congomortalitysurvey.pdf} [accessed 2016-7-21]",
}
