A rookie mistake on my part. I didn’t have the cups-pdf package installed at home. So when I tried to create a PDF of the Google Books PDFs — thus stripping them of extra data that made them unreadable — it wasn’t doing anything. I “reprinted as PDF” a book (in A5 size, to keep the margins approximately correct) and the result is satisfactory.
I’ve reinstalled Sigil, an EPUB editor, and I think I’m going to go back to by web roots. I started online by transcribing valuable but unavailable Unitarian and Universalist texts. (I was the first to publish Unitariana on the Internet: Channing’s Baltimore Sermon on Gopher; that is, pre-web.) The lack of edited Universalist EPUBs really bothers me. I think I will start with The Life of Murray, using a print copy I own. (To avoid the problem of trapped text in gutters.)
I’ve noted the copy of The Life of Murray before. It belonged to Minnie M. Moon of Blanchester, Ohio — a town in the southwest corner of the state. She got the book in 1899 as a Christmas present from “Vesta”. Minnie was the YPCU contact for the Blanchester church in 1895, attended the Young People’s Christian Union meeting in Akron in 1903, and opened the 1905 Ohio state YPCU convention, held at Blanchester, with a “Praise Service”. Sara Stoner would have been her minister for some time. She sounds like a young woman worth knowing. (There were once Moons at my first pastorate in Canon, Ga. I wonder if it’s the same family.)
