Luckily for me, the 2 small churches in Indiana that my German emigrant ancestors attended still have their old record books (albeit, one of them took the pages out of the books when the history committee set about translating them for publication). Anyway, one of the churches had them on their website previously. My reference note ended up looking like this:
St. John's UCC (Vincennes, Indiana), St. John's Record Book 1 (1858-1893), irregularly numbered pages, sectional entries in chronological order, section: Deaths, entry 109, Maria Meier, 10 March 1878; digital images, St. John's UCC (http://stjohns_ucc.tripod.com/stjohnsuccbk1.htm : accessed 08 Feb. 2020) > photo 132.
soon after that, later the same year actually, they changed their website completely including host and url and the images are no longer available through their new website. Sad.
I did contact them and luckily was put in contact with a member of their technology committee who sent me a USB key with ALL the pictures. Yay! And the images are the same. I know this because for the example above, Book 1, photo 132, entry 109...on the USB key there is a book 1 folder and photo 132 has the same entry for my great-grandaunt.
But, how to cite it now and for other entries going forward? Does it stay substantially the same until you get to the URL area? Would the following work?
St. John's United Church of Christ (Vincennes, Indiana), St. John's Record Book 1 (1858-1893), irregularly numbered pages, sectional entries in chronological order, section: Deaths, entry 109, Maria Meier, 10 March 1878; digital images, St. John's UCC, images provided via USB key by [name of member, Technology Committee] in August 2020, Book 1 > photo 132.
Can I remove the second "St. John's UCC" (the one in italics)?
For what it is worth, they are currently St. John's United Church of Christ. At the time of the records I am using, they were known as St. John’s Evangelical Church and/or German Evangelical St. John’s Church. So the "St. John's" at least has been consistent since 1849.
The current church website is: https://www.myucc.org/ but again, the photos of the old record books are not present.
