Over the centuries, thousands of pamphlets have been published to serve various purposes. Some have been preserved by individuals and prescient institutions, but countless others have disappeared forever. Harvard University's Widener Library has over 5000 pamphlets from 19th and 20th century Latin America, and until recently, they remained uncataloged and mostly inaccessible. Visitors to this site can browse the collection by title, subject, name, and genre. The materials offered here range from documents on accounting practices to those dealing with yellow fever. Additionally, visitors looking for descriptive documents that describe unexplored territories and the relationship between church and state will not be disappointed. The site also contains a nice help feature and visitors can also email questions to staff members at the library.
