You may not be aware, but earlier this year, FamilySearch announced a free lookup service for genealogy books and microfilm available at the renowned Family History Library in Salt Lake City. The response to this offer was overwhelming, 1000s of people contacted the Library to take advantage of this free service. Another way to utilize this service is to start with a limited preview of Google Books and the Library will then scan the entire page and email it to you for free.
This process is explained in detail in a blog post by Nathan W. Murphy.
