I am also new to genealogical citation. I got your reference EE and have been studying it. It is a great reference! I also read the recent posting about "Passenger Lists on Ancestry.com citing NARA -- Arrival by Aircraft" and found it to be very informative.
However, I still have a question regarding the correct usage of semicolons when a NARA citation is used along with the citation for the derived online images from Ancestry.
It seems like the source of the source part of the citation should be separated from the source part by a semicolon. However, the NARA citation itself has an internal semicolon.
So there would be confusion. See below:
"California, Passenger and Crew Lists, 1882-1959," database with images, Ancestry, (https://www.ancestry.com/search/collections/7949/ : accessed 9 October 2020), Description: “A3619 - Los Angeles, 1957-1964”, NARA Roll Number: 134, MAR 6, 1961, Airline & Flight: PAA 516, Robert A Stowe; citing NAI 2788930: Passenger & Crew Manifests of Airplanes Arriving at Los Angeles, California , 12/1/1957 - 11/3/1969; Record Group 85: Records of the Immigration and Naturalization Service, 1787-2009; National Archives, Washington, D.C.
Is there a better way to handle this situation?
Do you see any other improvements to be made to the whole citation?
