The first book of Baruch is counted among the apocryphal books of the Old Testament. The other three are counted among the pseudepigrapha.

The first book of Baruch (often called Baruch) was probably originally written in Hebrew, but it is no longer extant in that language. The original language of the epistle of Jeremiah is debated; was it Hebrew or was it Greek? This epistle is sometimes tagged onto Baruch as a sixth chapter and sometimes made to stand on its own, leaving Baruch with only five chapters.

The second book of Baruch is also known as the Syriac apocalypse of Baruch, though there are also Greek and Latin fragments. The third book of Baruch is also known as the Greek apocalypse of Baruch. The fourth book of Baruch is also known as the Remainder of Jeremiah, or paraleipomena Ieremiou.
