If you click on the link above, entitled "1967 Dominican Breviary in English" you will be taken to a table of contents page. Each entry in the table is a hyperlink to pdf texts of the breviary. The table of contents is arranged in the order that the actual breviary is arranged.
In the 1967 English edition, all of the preliminary texts, Ordinary, Psalter, Commons, Appendices, etc., are the same in both editions. The only thing that changes between the two volumes is the Proper of the Seasons, and the Proper of the Saints. In addition, at the end of the Proper of the Saints in Volume II, there are two sections with additional office texts.
The first is called "Office of the Saints O.P." whose feasts are in some places celebrated with I or II Class rank, For the Second Order. So this section contains texts for additional lessons for Matins, or 1st Vespers, etc., so that the office of the saints can be celebrated as I or II Class.
The second is called "On The Missions", and contains additional office texts for the saints associated with the Missions, so that they can be celebrated in certain places as I or II Class. These saints are St. Teresa of the Child Jesus, and St. Martin de Porres, O.P., and Bl. John of Vercelli, O.P..
WARNING: Some of the files are rather large (in excess of 100 MB) and the pdf viewer on your browser may not support a file that large for preview. If that happens, you can simply download the file. Please let me know if you find any missing pages, or double pages. I will fix them as soon as I can.
Perhaps, some day, I can do the same thing for the 1962 Breviarium SOP, so that both editions will be online for anyone who wishes to do research or possibly even use them to pray.
Veritas!
