One of my research projects has me tracing the emergence of a technology from the the 1940s to the present. As part of that effort, I have been looking for historic annual reports of the companies involved. This has proved somewhat more difficult than I would have guessed. Below are some sources I’ve identified so far. If you have other suggestions, please send me a note!
Purdue University Annual Reports Search Engine: Allows you to search 13 libraries, including Alabama, Berkeley, Columbia, Cornell, Harvard, MIT, Purdue, Stanford, Yale and others.
Columbia University Historical Corporate Reports: This pilot project resulted in the digitization of 770 annual reports from approximately three dozen companies based in the greater New York region. Overall, Columbia’s collection of paper reports includes more than 4,000 companies and predates the 1934 Securities Exchange Act. An Excel index to the collection is available.
University of Pennsylvania Corporate Reports: Penn’s library provides online access to annual reports for 40+ companies.
MIT Annual Reports Collection: MIT does not currently offer digital access, but it does hold a collection of more than 33,000 paper reports from over 2,400 companies. An Excel index to the collection is available.
