End of Evangelion Psalms is a 1997 book by Gainax apparently. It is a collection of select dialogue from the select episodes of the series with some minor commentary inserted.
In keeping with Eva's usage of religious symbolism, a psalm can be referred to as:
1. (religion, music) A sacred song; a poetical composition for use in the praise or worship of God.
2. One of the hymns by David and others, collected into one book of the Old Testament, or a modern metrical version of such a hymn for public worship.[1]
This book is apparently by doujin artist Nobi Nobita[2], author of Bridal Veil.[3]
