Cummings' semi-critical edition of the BCP is a fantastic resource, containing the text of the 1549, 1559, and 1662 editions of the BCP (the historically most important editions), though not replicating text which is identical in all three. The full text of 1662 is included, and elements of 1549 and 1559 widely differing from it are included separately. The work thus has sort of three main sections, depending on whether you wish to read 1549, 1559, or 1662. Plus of course an exceptional introduction from Cummings (similar to what his VSI with OUP presents). In addition several appendices flesh out some complexities with the black rubric and additional orders of service. One of the most useful sections of the book is the large section of detailed explanatory notes. These are bit complicated to navigate in the physical edition. Notes are organized by which of the three main sections you are in (1549, 1559, 1662). So you sort of have to know which section of the book you are in to know which section of the notes to turn to. Then, they are not numbered in the text, the text instead having a small circle symbol, so to locate the appropriate note in the Explanatory Notes section, you must know which subsection of the three main sections you are in, then navigate to that section, and locate the specific note by use of a cue phrase. This is complicated enough in the physical book. Logos could make this process astoundingly simplified, with each endnote symbol containing a hyperlink which both previews the note when single clicking and takes you directly to the appropriate section of the explanatory notes when clicking inside that preview for "more." Sadly, and strangely for what bills itself as a Logos "Research Edition," none of the endnote indicators are hyperlinked at all. The endnote circle symbol is included as plain text. The reader must perform the same complex navigational task as he would in the physical book to find the appropriate note for the section he is reading. As these notes are perhaps the most valuable part of Cummings' edition, Logos has missed a chance to take a wonderful resource and make it exceptional. Or put another way, they have missed an opportunity to simplify the unusually complicated navigational reading task and simplify it with the technological savvy their resources typically display. (Hyperlinks do exists and work it the product, for example, in the four different table of contents, where relevant hyperlinks navigate you to the appropriate section of the book.) I am not at all saying not to buy the product. Cummings' semi-critical edition of the BCP is one of the best forms of the BCP for the historian to use. It is worth having in your Logos library. Just don't expect some of the niceties you would normally get from a Logos edition.

The book itself is exceptional. Focuses largely on a Ladd-like understanding of inaugurated eschatology, and the reformation emphasis on glory of God. Like all Logos works, hyperlinked scripture texts are awesome. As are most other primary sources if one owns them (DSS, etc). However, note that many (most? All?) of the secondary works are not linked. Even if one owns them, the footnote citation doesn’t link to them. It doesn’t even link to an abbreviation glossary, or to the bibliography. Because Schreiner identifies each work only by last name and date, if one wants to even know what work is being cited, they must move to the bibliography and skim till they find it. (And even then, even if they own it, it may or may not be linked to in the bibliography) dictionary articles seem to be usually, commentaries always are. Many monographs and other works are not. The ability to glance at a work cited in a footnote, and to open that work directly if one chooses, is the most valuable part of reading a work on Logos imho. So buyer beware that this normally amazing feature of logos works seems to be rather limited in this work for some reason.
