The previous poster was noting differences between different traditions of the Divine Office, and comparing online versions of the current Roman Rite version with other avaialble versions.
I believe that does not answer your question.
I Live in the UK, and the publications are nation or region specific.
Here we have
"A Shorter Morning and evening Prayer"
This is the 4 week psalter, with Morning, Evening, and night prayer, but without the most of the proper of the seasons or any of the feasts of memoria.
"Morning and Evening Prayer"
This is everything you need to follow Lauds, Vespers and Compline (Morning, evening and night prayer). It has the full proper of the seasons for those sections. It has the (shortened) General Instruction (Omitting sections not related to those 3 hours). It has the general calendar for the region, and the National calendars for the countries where it is intended to be sold (In this case the Nations within the British Isles: Ireland, Scotland and England & Wales)
"Daily Prayer / Prayer During The Day": this is a small book containing the 3 "Small Hours" of the days' prayers. (Terce, Sext & None). Very convenient if you want to carry it for prayer of The Office during your working day
This contains everything except the Office of readings. It's a bit bigger than "Morning & Evening Prayer, as it also contains "Daily Prayer"
"The Divine Office" (As a 3 or 4 volume set)
This contains Everything you need *including *the Office of Readings.
I am not aware of a printed publication of the Office of readings other than the full "Divine Office".
You will note that it adds 2 or 3 volumes to the set compared to "Christian Prayer"
The UK & Ireland version is published by Harper Collins. Most reviews comment that it is of lesser print quality, and I can attest that the "Morning & Evening prayer" while well bound, has misprinted pages, and I have 1 copy where around 2 dozen pages were blank, scattered through weeks 2 & 3 of the psalter. Both copies I hav contain some pages where the print is smudged or very faint.
There is a almost identical version published by Veritas in Ireland (an official catholic publishers) I have not seen their print quality.
(I now personally boycott Harper Collins, as I discovered they are 100% owned by Rupert Murdochs News Corporation. I have written to our bishops asking them to reconsider who gets the uk publishing rights for liturgical publications as there are several catholic publishers and I believe the exclusive rights to a major publication should not lie with a commercial publisher who has such a scandalously tarnished reputation.)
The USA have at least 2 publishers of the smaller versions. The 4 volume edition is by St. Josephs Press. It contains variations in the translation compared to the UK editions, and also contains some additional "Psalm Prayers"
*Personally I very much prefer the translations used in the UK edition where they are different. - they are far more poetic. - and very occasionally they are slightly easier to understand. *- but the additional materials in the St Josephs version are very usefull additions.
If you wish to pray in common you must use the correct version approved for your country.
A new translation is in the works (whether for just the United States or for the whole English-speaking world I'm not sure) but the process only began recently so I would not recommend anyone wait for it to come out. It may save money not to have to buy two editions within a just few years, but in my opinion depriving oneself of this prayer for years is too high a cost.
