The ANALEKTA B' and C' (Volumes VI and VII) of the series THEORY AND PRACTICE OF CHURCH MUSIC by Georgios N. Konstantinou have been released, containing Cherubic and Communion hymns by various teachers as well as compositions by Iakovos the Protopsaltis.

They largely meet the needs of both the fourth-year students of the Curriculum of conservatories and schools of Byzantine music and those who serve in the sacred ambons.
