First mention of the "book" as we know it today

Found on page 35 of The History and Uncertain Future of Handwriting

"...the first reference to the 'book' as we know it today comes from the poet Martial, who lived from c38-102 C. E. 

Whoa, that's enough now

whoa, little book!

We've come now right

to the end.

You're keen to keep

going any further,

and you can't be held

back on the last page,

As if you hadn't finished

the task

That was finished already

on the first page.

Now your reader is 

grumbling and giving up,

Now even the scribe

himself is saying

'Whoa, that's enough now, 

whoa, little book!'"
