Studies in Biblical Literature
Recently I came across a series called Studies in Biblical Literature in which I found some interesting Psalm related books:
The Narrative Effect of Book IV of the Hebrew Psalter by Robert E. Wallace.
Text and Concept Analysis in Royal Psalms by Randy G. Haney.
The Book of Psalms Through the Lens of Intertextuality by Beth LaNeel Tanner.
The King-Priest of Psalm 110 in Hebrews by David R. Anderson.
