This is interesting, from the June issue of the BCDW newsletter: the bishops’ committee has endorsed the idea of a “Book of the Chair” for use by Mass celebrants.
Regarding the 2011 Roman Missal, the national liturgy office “has received numerous comments on the unwieldiness of the book, particularly for younger altar servers, due to its substantial size and weight.”
Given a choice between a missal with just the texts needed on Sundays and solemnities, or a book with just the texts needed at the chair, the bishops’ committee endorsed the second option. Other conferences have undertaken a similar project.
This is interesting because some years ago it was absolutely verboten by Rome to create new genres of liturgical books not based on the official Latin edition. Happily, it seems that commonsense is prevailing now.
