What were they thinking? Read Matt Smith's Miller-McCune.com exploration of UCSF's Legacy Tobacco Documents Library. The constantly expanding archive holds 40 million pages of secret corporate memos, privileged legal communications and other documents obtained through discovery processes from a decade of successful lawsuits alleging that the industry had lied about tobacco's health effects. The documents demonstrate how the industry pioneered modern techniques for manipulating politics, scientific research and public opinion. As a result, the library is something of a Rosetta Stone that reaches beyond the tobacco industry to assist anyone seeking to decipher how business, politics and media function.
