I found a very interesting book design in the TeX showcase (pp.pdf/pp.tex):

• Does the source really have enough information inside to produce such nice formating?
• Can this format be readily applied to a LaTeX document?

Does the source really have enough information inside to produce such nice formating?

No it hasn't. It contains just the mark up and neither the drop-capital image, nor the corresponding style. The font is missing as well.

Can this format be readily applied to a LaTeX document?

What do you exactly mean by readily? As it is, without any changes? Then the answer is no. But I'm quite confident that a similar result can as well be achieved using LaTeX markup.

A header to roughly obtain the format of the book might be the following:

```%\usemodule [simplefonts]
%\setmainfont [Jenson] % I don't have Jenson

\usemodule [lettrine]  % For the drop cap

\definepapersize [custom] [width=152mm, height=229mm]
\setuppapersize  [custom]

% Blindly guessed
\setuplayout
[
backspace=2.8cm,
width=9cm,
height=18cm,
location=doublesided,
]

\setupindenting     [yes, small]
\setuppagenumbering [location=bottom, alternative=doublesided]
\setupbodyfont      [10pt]

% Needs to be fixed with proper markup
[\midaligned{\italic\getmarking[chapter]}] []
[] [\midaligned{\sc Pagan Papers}]

\starttext

\chapter{A Bohemian in Exile}

\midaligned{\sc A Reminiscence}
\blank

% I don't have this image
%\placefigure[left]{none}{\externalfigure[w20]}

% Compensate for missing drop cap
\lettrine [Lines=4] {W}{ hen}
many years ago now, the once potent and extensive kingdom of…
[…]
\stoptext
```

This should just considered to be a starting point. The markup of the source should be improved and properly divided into chapters/sections, to make the correct phrases appear in the headers.

• No, it seems like a part of a larger project, it doesn't even have `\starttext...\stoptext`, and non of the style used is present in the file either, so I think it is by it self is pretty useless and tells nothing.
• I've no idea
