Any corporate annual reports the UChicago Library has in print are integrated in the bookstacks collection and are included in the Library Catalog.
Choose the advanced search, enter the company name in the author box, and "annual report" in the title box. You may need to use just "report". You can then use the limits to limit by author to your company.
For example, the library holds the annual reports of Ford Motor Company for 1955-1964, 1967, 1969.
