So, when I care about a book, I never read Standard Ebooks' edition.
By the way, the modernization is more than joining a few words. Sometimes, Standard Ebooks replaces the word used at the time the book was written. For instance:
This time, however, the mountain was going to [-Mahomet;-]{+Muhammad;+}
The previous quote is from Galsworthy's "Forsyte Saga". The author used many French words and French spellings – like "Tchekov" for the Russian playwriter that was living in Paris. These subtleties are lost with the modernization.I also think some alterations are plain mistakes. For instance in the same book:
if she wanted a good book she should read [-“Job”-]{+Job+};
his father was rather like Job while Job still had land.
