Please read this article: www.familysearch.org/ask/salesforce/viewArticle?urlname=Affiliate-Library-needs-access-to&lang=en If guests are using a computer in the Family History Center or a computer in a connected public library, they can view the images. Do not sign up for FamilySearch.org. (If my local library were affiliated, I would check it out for myself, but there is no affiliate near me. My nearest center is one of the large regional FHCs which is a FHL.) Some of the digitized books on FamilySearch.org have limits to display. When a scanned item comes with “ExLibris Rosetta” in the upper-left corner and an error message in the center of the screen, the content comes from a scanned book with restrictions that do not allow users to view in a partner library.
