@GWarner First, search the internet, which apparently you've done. Then look in your local library catalogs. Once that fails, ask the internet. You may ask us here, but there are dedicated forums like
en.wikipedia.org/wiki/Wikipedia:WikiProject_Resource_Exchange/… . Alternately, become internet-famous so that thousands of people read your blog, and then ask your blog readers, offering them a small bounty, such as adding them to your public hall of fame.
