Today, the feast of the Seven Sorrows of Our Lady, our own Ben Yanke has published a new website with the full text of the Little Office of the Virgin Mary, including the special forms of it said in Advent and the Christmas season: https://www.lobvm.com/ Under settings, the Hours can be set to two different versions, pre-Divino Afflatu (1910) or 1962. To say the Office according to the Divino Afflatu reform, set it to 1910, and omit Psalms 66, 149 and 150 from Lauds. In 1962, the antiphons are all doubled, where they were traditionally semi-doubled, and there are a couple of other minor differences. Ben also has a website with a much simpler Little Office, that of the Sacred Heart (https://www.littleofficeofthesacredheartofjesus.com/), and he is planning on creating more such sites in the future. Feliciter!
