Some time ago, FamilySearch announced a FREE Lookup service whereby they would scan pages of books found in the Family History Library for patrons who couldn’t actually get to the library itself. They have now published a blog explaining in detail how one can use Google Books to find family in the Google snippets of copyrighted volumes. If the book is still under copyright, and not available as a full book on Google Books, you can have the Family History Library take a scan of the page you need, even if it’s not available at Google Books. The blog is very detailed, giving step-by-step instruction.
You may also download a full-color pdf file of the post to use as a handout.
Thanks to ResearchBuzz for the heads-up.
