1928 Book of Common Prayer,
Anglican Missal (People's Edition),
1890 marriage manual [sex-ed book from 1890]
bunches of wedding-planning books [most helpful by far was the one written for wedding photographers, not brides] and Rome/Italy travel guides. I also did a bunch of additional liturgical research trying to write our ceremony programs. You wouldn't think it'd be so hard to figure out how those first 2 listed mesh for a wedding!
