These books list sisters' assignments for each sister by order (approximately) of the sisters' arrival in America or entry into the community in America. Two sisters are recorded on each page. For each sister are given religious name, places of assignment, dates of assignment in one of two columns ("as subordinate" or "as superior" of mission), and date of vows or renewal of vows. Other information, such as baptismal and family names, date and place of birth is often included under religious name. The fact and date of death or departure are also generally noted. Entries for sisters who have died or left are crossed out with a single diagonal line. Some entries are continued on later pages to which the reader is directed. The first volume contains sisters who arrived in America or made first profession the community between 1868 and 1903, inclusive. The secondgives three sisters per page and contains sisters who arrived or professed between 1904 and 1961. There are incomplete entries for six sisters who were invested (received) in 1960. A recently compiled index to Volume 1 alphabetized by sisters' religious names is located with the volume.

Both volumes are indexed in 240/02 and 113/22. At the back of Volume 1 of the Sisters' Assignments, beginning on p. 236, there is a Death Register, described below.
