The 
Federal Reserve Bank of St. Louis, through its 
FRASER (Federal Reserve Archival System for Economic Research) project, aims "to provide timely and convenient data to scholars, analysts, students and  interested observers of the U.S. economy."  Unique among the documents digitized is 
75 Yrs. of American Finance: A Graphic Presentation, 1861-1935, created by L. Merle Hostetler of the Federal Reserve Bank of Cleveland in 1936, and later expanded to include the years 1936-1938.  
"The entire book consists of a chart, approximately  85 feet long, fanfolded into 40  pages with additional years      attached to the last page.  It also includes a 'topical index' to  the chart      and some questions of technical interest" that can be answered by  consulting the chart.  Concurrent economic and political  events are detailed for each year. Some sample pages:

Many of the events listed are of course well known, such as the introduction of the Bessemer process in the United States (1864), the Credit Mobilier scandal in 1872, and the creation of the TVA in 1933.  But the lists of information less commonly known, particularly juxtaposed in the time line format, provide a unique visual aid: for example, the fact that glass mason jars were supplanting crocks  for fruit preserves (1864); the existence of an "epizootic epidemic" among horses that impeded trade (1872); the beginning of  construction of the San Francisco Bay bridge (1933).
