This document provides instructions for using the My Source Box tool on FamilySearch.org to organize genealogy sources. The My Source Box acts as a holding area for sources found during research. Sources can be added directly from search results on FamilySearch or from other websites by manually creating source records. Sources in the My Source Box can be organized into folders and attached to specific family members in a user's Family Tree. The tool allows users to easily gather, organize, and attach important genealogy sources during online research.
