What is the oldest possible book anyway?

It probably should be this work from 1842:

Sketch of
The Analytical Engine
Invented by Charles Babbage
By L. F. MENABREA
[...]
With notes upon the Memoir by the Translator
ADA AUGUSTA, COUNTESS OF LOVELACE

which reputedly contains the first-ever computer programme — except that it’s too short to be a book. :-(

So it’s quite possibly this book from 1864:

Passages from the Life of a Philosopher by Charles Babbage

in which Chapter VIII is devoted to the Analytical Engine.
