Hello Light friends! I just found a goldmine on the LDS church site familysearch.org. If you're looking for the Searchlight newsletter originally published by Betty M Light Behr (now edited by Christopher Light), the LDS Church has it in digital form on their web site! This is really exciting given the newsletter is rather hard to come by.
I would post the link but it's long and may not work. Just search the catalog at familysearch.org for "Search light : Light (and variant) family newsletter"
authors: Behr, Betty M. Light
Light, Christopher J.
Scroll way down past the description and surnames list for the list of volumes/issues. The first item is a surname index titled "index v. 1-6 (1979-1985)" and is available for digital browsing. The ~7th item down listed is "v. 1-14 (1980-1993)" and that is your link to the digital copies of most volumes and issues that Betty Behr compiled.
Also check out "v. 22-29 (2001-2008)" which contains a page with links to those individual volumes and issues from 2001-2008 edited by Christopher Light.
Happy researching! I just had to take a break from printing relevant issues to share the good news with you all.
