From the website of the Personal Ordinariate of Our Lady of Walsingham:
The Coverdale Psalter will be included, as will lectionary tables which closely follow the not as yet well-known, but superb, two-year sequence of Scripture readings devised for the daily Office of the Roman Breviary. There will also be the Ordinariate Calendar and, most notably, a rich anthology of post-biblical readings drawn from the riches of the British spiritual tradition. This anthology complements the Roman Divine Office as well as the Ordinariate Office, for it will be possible to use many of the post-biblical readings for the Office of Readings.

Some will find themselves using the different Office books for different purposes – one for individual prayer and devotion, the other for public worship. Those who want to use the Roman Office books in the morning and the Customary in the evening – or the other way round – will be able to do so without too much difficulty. The particular value of the Customary is that it makes available one of the acknowledged treasures of the Anglican tradition – the public celebration of the Office, and in particular of Evensong. The reform of the Roman Office following the Second Vatican Council sought the development of the public celebration of the Office and, truth to tell, that is a reform yet to be realised. In these early days of the Ordinariates, there have been already many celebrations of Evensong and Benediction and it is intriguing to know not only that this has been in accordance with the Holy Father, Pope Benedict’s wish, but also that it has been his great pleasure, that this should have been so.
It is hoped that the Customary will be ecumenically helpful too. There has been a deliberate decision by the Holy See that the Ordinariate’s distinct Use should be predominantly in traditional language. This is not to criticise in any way the modern language translations and compositions of recent Anglican revisions. Rather it is a recognition of the value of the sacral language of the Prayer Book... (continued)
