Company Research: Company Histories

Researching company histories

  • Twentieth century U.S. company histories can be challenging to trace because much of the information prior to 1990 is not digitized and remains in print, microfiche or CD formats.  
  •  U.S. public company issued annual reports and their filings with the U.S. Securities and Exchange Commission (SEC) are one of the best sources for company history but no institution has a comprehensive annual report collection.   ProQuest’s Historical Annual Reports cover only 800 companies.  Electronic company filings with the U.S. Securities and Exchange Commission (SEC) are accessible only from about 1996, while earlier documents, if available, can only be requested from the Commission’s office.  Most of the annual report collections of the major research libraries are limited in size and are not digitized.
  • In the twentieth century Moody's Manuals and Standard and Poor's Corporate Descriptions were the core sources summarizing business and financial information about U.S. public companies and major foreign corporations.  Annually since 1906, Best’s Insurance Reports published the financial condition of major U.S. insurers.   
  • Mergent, Inc. purchased the Moody’s Manuals enabling their content from the early1900s to the present to be electronically accessible through the Mergent WebReports.  Contact a librarian if the digital copies are not readable or are omitted.
In June, 2014, the Kresge Business Administration Library will only offer electronic resources.  Its print, microfiche, and CD materials* will be permanently moved to the University of Michigan Library or the Law Library.  Before beginning your research, consult a Kresge Librarian on the availability of these resources.
