Breadbooks

To make a breadbook, one first uses a special slicing machine to cut the bread almost -but not entirely- through, leaving a 'hinge' at the side.
The best side to use for the hinge is the flat base.
Then, one adds text (and perhaps images) onto the sides of each slice. using an inkjet loaded with edible ink. The breadbook has to be opened to each non-blank slice for print-head access.
The outer side of the crusts may go unprinted; I recommend using a patterned mould when baking to emboss the title of the breadbook on the 'cover'.

Single bread-eater households (and those who are willing to peruse each other's bread prior to consumption) can have an entire story told throughout the loaf.
Multi-occupation households may buy breadbooks where each page has a single short story.
