Expanded Article - Chain of Lineage

The Chain of Lineage is the introduction appearing at the beginning of the Hayom Yom calendar, and it contains the history of all Chabad Rebbes, their activities, their books, and their family members.

This introduction was privately edited by the Rebbe, and over the years with each new edition that was published, the Rebbe edited the updated Chain of Lineage with details relating to his activities during the years that had passed since the previous edition. The last editing was done in 5748 (1988).
