FamilySearch digitized books

Hello, NextGenHistory. You ask:

Since FamilySearch has digitized and "published" it online, I can treat it like a published book when citing it, right?

Yes. You would cite the original book in Layer 1, your source layer. Then you cite FamilySearch in Layer 2, your access layer.

You also ask:

Would the below citation be correct in this instance? .... 1925 is the year the original was produced, but I can't tell when FamilySearch "published" it online. 

William Prescott White, A Study in Ancestry Being a History of the White Family of Honey Brook, Pa., 1925 (Salt Lake City, Utah: FamilySearch International, publication date unknown), 10; imaged, FamilySearch (http://www.familysearch.org/library/books/idurl/1/168692 : accessed 25 June 2024).

The issue of publication details is where your citation goes astray. You have two separate sets of publication data to identify.

• Layer 1 identifies the original book and its publication data.
• Layer 2 identifies the online provider of the images and its publication data.

Publication data for the FamilySearch website should not appear in Layer 1, where you are citing the original book. This is addressed in EE4 in the "Building a Citation" chapter, specifically 3.16: Sequence of Layers:

THE RULE THAT HAS NO EXCEPTION

The mix-and-match nature of citations to online images has one cardinal rule: Details that describe one entity must not be attached to a different entity. Think of this as a Velcro Principle for online citations: what’s meant to stick together should stick together.

Standard book format for citations in the humanities, regardless which style guide you follow, takes this form:

Author, Title of Book: Subtitle (Place of Publication: Publisher, Date), specific page or item.

No publication data is provided on the pages of your original book, as you've noted. EE4 13.15: Publication Facts > Details Missing explains and demonstrates how to handle situations in which a book does not identify its publisher or its place of publication.

All things considered, the edited citation would be this:

     1. William Prescott White, A Study in Ancestry: Being a History of the White Family of Honey Brook, Pa., 1925 (Salt Lake City, Utah: FamilySearch International, publication date unknown (No Place: No Publisher, 1925 ), 10; imaged, FamilySearch (http://www.familysearch.org/library/books/idurl/1/168692 : accessed 25 June 2024).

The "clean copy" would be this:

     1. William Prescott White, A Study in Ancestry: Being a History of the White Family of Honey Brook, Pa. (No Place: No Publisher, 1925 ), 10; imaged, FamilySearch (http://www.familysearch.org/library/books/idurl/1/168692 : accessed 25 June 2024).

Re the highlighted issue above (the needed punctuation between the book’s title and the book’s subtitle):  See Chapter 13: Publications, specifically, 13.21 Titles > Basic Principles:

“In a well-punctuated book title, a colon typically represents the break between the main title and the subtitle. That break is commonly a stopping point for the shortened title.”
