In this section the majority of the Psalms are of the Sons of Korah. The story of who Korah is can be found in Numbers chapter 16. The Sons of Korah were Levites who were responsible in part to the music in the tabernacle/temple. We also have the only Psalm of David found in Book 3, Psalm 86. We see the lovingkindness of the Lord, and that His lovingkindness extends to all the nations of the earth.
