Dear Batushka,
Our Church uses wonderful Vespers books, with music in English, prepared by John Vernoski. They contain all the sticheri in the eight tones. They are quite good. He has also prepared a very useable book for Sunday Lenten Vespers.
I do not think there has ever been an 'officially' promulgated text for the Byzantine Church's Vespers or Matins. The Uniontown books are 'unofficial' and privately circulated, published by the nuns, not the Church. However they are generally respected works.
The material from John Vernoski's books is mostly taken from there. But arranged for congregational use.
I highly recommend them. They were introduced here, with great success, and there is quite a 'Vespers' following.
Elias
