I don't know anything about the material itself so no comment, but just correcting one small trivial detail

"This is 290 pages of content plus intro and table of contents -- this can be done as a 296 page volume"

There are no 296 page Masterwork volumes. They go in 16 page signatures, so they go from 288 page volumes to (next biggest size up) 304 page volumes.
