The World War I Collection at the University of Colorado in Boulder presents some 1,200 digitized pamphlets. You can search the collection using a free text search or the advanced search mode. You can also browse by title and subject, use a map and a timeline to find items, or choose a tag for a particular theme or subject. The pamphlets stem mainly from the United States, Canada and European countries. Some pamphlets contain the text of official documents, and thus give a look also at diplomacy. The wide range of the collection is shown by the presence of pamphlets in English published in China and Japan.
