A Family History Center is owned and operated by the LDS church.  An affiliate library can be any library that requests being an affiliate and is approved.  My local public library is an affiliate and it has been so convenient to request and read microfilm right where I live.  I have been very grateful to the Family History Library for this.Virginia From: Jackie Brown <celticsearch@comcast.net>   What is the difference between Family history center and family search affiliate library?
