Oh I understand that the actual prayers are not copyrighted, but the translations are, such as the Jordanville Prayerbook. However there are some texts such as the Hapgood service book which are no longer under copyright.
I am also trying to amass a large collection of various prayers. Prayers for not only meal time but also for such things as deliverance from thunderstorms, tornadoes, prayers for women with child, against evil thoughts, etc. There are a lot of the prayers I am looking for in the "Orthodox Prayers of Old England" prayerbook, however again the exact wording is copyrighted.
