A HISTORY OF THE AMERICAN LOCOMOTIVE 1830-1880 Ed. An excellent technical review of early engines - a valued addition to any collection. Copied hereafter are sections dealing with locomotives built during Hopkin Thomas' time; Garrett & Eastwick, the Nonpariel, anthracite coal utilization, chilled cast iron wheel construction, and drawings of selected engines of the time.

A year or so ago I picked-up "The American Steam Locomotives: Design and Development, 1880-1960" by William L. Withuhn. (2019) I purchased it primarily as a reference book and then sat down and read it cover to cover. One thing I learned was that it wasn't until the 1920's or so that "Science" began to rear its head in steam locomotive design, before that there was a lot of guess-and-by-golly and WAG's went into designing steam locos and just when steam hit its pinnacle in development, along came the diesel/electric and made it all irrelevant.
