The information provided varies, but at minimum the results include the company's address and a list of filing-types with dates.   

Secretary of State: Records

The Secretary of State's Office kept a number of different types of records related to businesses.  Many of these historical records are available at the Library, including:

  • Corporations Division
    • Indexes of Active and Inactive Domestic Corporations
      Gives corporation name, location, date of record (i.e., date when incorporation papers were first filed), volume and page number in the incorporation record books, and the date and number of the affidavit of publication of the incorporation notice. Subsequent amendments to the articles of incorporation or bylaws are often noted, as well, giving date, volume and page number, and nature of action.  The index is believed to date to the 1850s; however, the majority of entries appear to be for the 1930s and later.
