Hallo Don,
I made already a Book Review of the four book series and also of the planset.
The planset is NOT part of the book and has to be ordered separately, also because they planset is much younger than the books.
Here is the link to the Planset Review:
Planset Review: "THE 74-GUN SHIP" (31 + 11 plans) in scale 1:48 (or 1:72) 31 plans by Jean Boudriot and 11 Timbering plans by JC Lemineur The drawing set is available in scale 1:72 or in scale 1:48 - my set (showing here) is in scale 1:48 complete Drawing set or only the newer...

and here the link to the ancre page:
The 11 timbering plans (1/72 or 1/48) with a color 24-page booklet with a series of photographs illustrating the implementation of the framework. The essential complement to your 4 volumes. New 2019: Sail plans for 74-gun Ship at scale 1/72 or 1/48.

The plans by themself are not in english, or in any other language, but the small booklet attached. Take a close look at all my photos in the Planset review and you will know what you would get.
New are the four plans with the sails, which are available since very short time, but as I know highly requested by modelers.
