1. I found the institutional investors for the company I was investigating on Marketguide.com, which listed the top 10 Institutional Investors, as well as a wealth of other useful company information, such as insider stock holdings.

Also useful are the following websites:
Price's List of Lists
http://gwis2.circ.gwu.edu/~gprice/listof.htm

direct search  (invisible web databases)
http://gwis2.circ.gwu.edu/~gprice/direct.htm

and
http://gwis2.circ.gwu.edu/~gprice/state.htm  (plenty of California material). Thank you Gary Price for all of the above!

2. While I wasn't able to locate the SEC 13F filing for the company I was researching, I'm told the 13F filing contains information on Institutional Investors.

3. Dialog File 540 used to, but no longer has Institutional Investors (an FYI for those of you who remember being able to obtain such information in Dialog).

Addendum by Janet Hartmann, William Blair & Co.

Just to make this clear, the company doesn't file the 13F. Each institutional investor files a 13F each quarter, listing all the listed/NASDAQ companies it holds. You would have to check every 13F list for your company name. If you have Global Access, you can limit your search to 13F's and then full-text search for your company name. You would have to identify the most recent holding for every institution, then open the document and check the holdings list. But that's why CDA Prism (owned by the ever-growing Thomson info empire) is able to sell their product, in which you can enter a company name and get a list of the institutions who filed 13F holdings. I believe many secondary sources like MarketGuide, Bloomberg, etc. get their list of holders from CDA Prism.
