when I copy from a factbook, it does not include the attribution:
Jacob is the grandson of Abraham and the inheritor of the patriarchal promises to Abraham concerning possession of the land of Canaan (Gen 28:3–4, 13; compare Gen 12:7), abundant descendants, and blessing to all humanity (Gen 28:14–15; compare Gen 12:2–3). He is the third and last of the major patriarchs whose experiences with God form the basis for Yahweh’s later identification of Himself as the “God of Abraham, the God of Isaac, and the God of Jacob” (see Exod 3:6, 15; 4:5; see also 1 Kgs 18:36; 1 Chr 29:18, as “Israel”). Like many other figures from Israel’s early history, Jacob is unknown outside of the Bible. However, the customs and lifestyle of the patriarchs have been shown to be broadly consistent with that of the pastoral nomads of the ancient Near East in the Middle Bronze Age (see Hamilton, The Book of Genesis, Chapters 1–17, 59–67).
copying from the actual source does:

Seems copying from the factbook should include the attribution.
