To find information about the company's history, start with the database Gale Business Insights, accessible via the library page on Engage (see Databases A-Z button).
Type in the name of the company in the search box (or click on "Browse All Companies")and select your company from the list provided. Once the company profile page opens, look for "In-depth Articles" and select Company History.
In addition, check to see via a web search engine if the company has an official website. Once found, look on the company website for links referring labeled 'About' or 'History' (also check for the company's latest annual report, which also provides a concise history of the company).
