Final Note:
Many universities and organizations have digitized many items from their local Special Collections & Archives, and searching the open internet will often find these high quality collections. Try adding keywords to your search like "digital archive," or "university," to your searches to narrow your results down to these academic collections (and to get rid of some of the wacky results that the rest of the internet might give you.)
And don't forget - you can always ask for help! emp@uoregon.edu - Elizabeth
