The Octoechos in Church Slavonic
There are some differences between the Octoechos as used among the Ruthenians, and among the Great Russians. The variations are most noticeable in the sessional hymns of Sunday Matins. On the other hand, the Sunday Octoechos in the Ruthenian usage is readily available, while the weekday Octoechos is not.
The Velikij Sbórnik and the Basilian Vecernya i Utrenya contain the Ruthenian texts for the Sunday Octoechos, from Vespers on Saturday evening to Vespers on Sunday evening.
No new Octoechos was printed as part of the Ruthenian reform of the 1940's.

The Uniontown Office of Vespers contains a complete Sunday and weekday Octoechos for Vespers. The Uniontown Office of Matins provides a fairly complete Sunday Octoechos for Matins, omitting only the troparia of the second and third canons.
