A reader of this blog was kind enough to send along this weblink for an online archive of the 1941 Dominican Sister's Office Book.
This is a wonderful little book, which contains the entire Little Office of the Blessed Virgin Mary for Dominicans, as well as meditations on the pslams, canticles, and hymns of the office. Finally, it contains the propers for making a commemoration of each of the Dominican Saints and Blesseds throughout the liturgical year.
(Please note that this online edition is missing pages 112-131, so most of Terce and the beginning of Sext is not included.)
Anyone who is interested in viewing the book can do so by clicking on this link:
