"BYU access" means that the item is accessible on BYU campus or remotely for logged-in BYU students and faculty. If labeled “BYU campus” then it is available anywhere on BYU campus, but not remotely. "BYU Library" indicates that you may only access the resource while physically at the BYU Library. (If you have a personal account with any of these sites, you can access them anywhere. If so, it is best to access them directly rather than using these links.)

*FamilySearch is accessiable anywhere on the Internet, but many of the images (ca. 25-30%) require viewing at a FamilySearch family history center. BYU Library is also designated as a family history center allowing access to these images.
