The is exactly the same Lectionary for the Order of Preachers, containing the Mass readings for Dominican saints and votive Masses, as in this large-size edition:

But it has been reformated to a smaller (6 x 9 inch) size for use in small chapels and for travel. Do remember that like the volume as a whole, the typeface is smaller than in the full-sized edition. And because of the resizing of the pages there will be a very large upper margin.
