The University of California, San Francisco Library and the American Legacy Foundation recently released the Legacy Tobacco Documents Library (LTDL), a collection of more than 20 million previously private documents from tobacco industry files. Ranging from approximately the 1950s to recent years, LTDL offers searching, viewing, and downloading of documents, covering projects central to the tobacco industry like marketing, research and development, cigarette analysis and design, as well as industry efforts to establish business in developing countries. Within the next 18 months, more documents will be added to the already extensive collection. Currently, viewers may perform simple or advanced searches; view documents in Adobe Reader format (.pdf) or tagged image file format (.tif); or for a quick look, utilize the page-by-page option to view .gif images within the browser.
