Anyone have an encyclopedia? If you do, please read!?

Hey I am doing a report and I was just going to use an online encyclopedia, but my teacher apparently needs the page and volume number I'm using. So if anyone happens to have an encyclopedia laying around, PLEASE look up Beethoven for me and tell me the name of the encyclopedia, the volume number, and the page number you find it on. I would be ETERNALLY in your debt lol. PLEASE HELP ME!!!!!!!!
