If you'd like to search for something historic online without bothering the Master Researcher® or me, you can try the stunning HATHI TRUST website.
"HathiTrust is a partnership of major research institutions and libraries working to ensure that the cultural record is preserved and accessible long into the future".
They have more than 50 collections represented, and you can search from that page (upper right) or click HOME (upper left) to go to a more specific search page. The search results aren't as easy to use as those on Google Books OR Internet Archive. Still, its a valuable resource...which Larry found.
