I searched for "Stegosaurus" and got _Osteology of the Armored Dinosauria_ by Charles Whitney Gilmore , 1914

A link to the internet archive copy, bc reasons:
https://archive.org/details/osteologyofarmor00gilm/page/n6/mode/2up

I think this volume is still referenced by paleontologists working on stegosaurs today; see for example the description of Miragaia

https://pmc.ncbi.nlm.nih.gov/articles/PMC2674496/pdf/rspb20081909.pdf

and search for Gilmore
