There are a couple of poetry about book and reading that you need to learn about. So many writing advice, especially writing advice about poetry, tells you to read as much as you can possibly get your hands on.

Anyone who composes often reads often. So what better subject is there for writers to write about? Poems about books are charming and fun.
There is plenty of writing about books, or that are book adjacent or inspired. Poets are always borrowing from stuff that they have read. Maybe you can borrow some inspiration from these poems!
Poems About Book
Here are a few, in my opinion, of the best poems about books:
There is No Frigate Like a Book by Emily Dickinson
There is no Frigate like a Book
To take us Lands away
Nor any Coursers like a Page
Of prancing Poetry –
This Traverse may the poorest take
Without oppress of Toll –
How frugal is the Chariot
That bears the Human Soul –
from The Collected Poems
Ode to the Book by Pablo Neruda
When I close a book
I open life.
I hear
faltering cries
among harbours.
Copper ingots
slide down sand-pits
to Tocopilla.
Night time.
Among the islands
our ocean
throbs with fish,
touches the feet, the thighs,
the chalk ribs
of my country.
The whole of night
clings to its shores, by dawn
it wakes up singing
as if it had excited a guitar.
In the Library by Charles Simic
There’s a book called
“A Dictionary of Angels.”
No one has opened it in fifty years,
I know, because when I did,
The covers creaked, the pages
Crumbled. There I discovered
The angels were once as plentiful
As species of flies.
The sky at dusk
Used to be thick with them.
You had to wave both arms
Just to keep them away.
Now the sun is shining
Through the tall windows.
The library is a quiet place.
Angels and gods huddled
In dark unopened books.
from Sixty Poems
Books by Elizabeth Barrett Browning
Books, books, books!
I had found the secret of a garret-room
Piled high with cases in my father’s name,
Piled high, packed large,–where, creeping in and out
Among the giant fossils of my past,
Like some small nimble mouse between the ribs
Of a mastodon, I nibbled here and there
At this or that box, pulling through the gap,
In heats of terror, haste, victorious joy,
The first book first. And how I felt it beat
Under my pillow, in the morning’s dark,
An hour before the sun would let me read!
My books! At last because the time was ripe,
I chanced upon the poets.
As the earth
Plunges in fury, when the internal fires
Have reached and pricked her heart, and, throwing flat
The marts and temples, the triumphal gates
And towers of observation, clears herself
To elemental freedom–thus, my soul,
At poetry’s divine first finger-touch,
Let go conventions and sprang up surprised,
Convicted of the great eternities
Before two worlds.
Good Books by Edgar Guest
Good books are friendly things to own.
If you are busy they will wait.
They will not call you on the phone
Or wake you if the hour is late.
They stand together row by row,
Upon the low shelf or the high.
But if you’re lonesome this you know:
You have a friend or two nearby.
The fellowship of books is real.
They’re never noisy when you’re still.
They won’t disturb you at your meal.
They’ll comfort you when you are ill.
The lonesome hours they’ll always share.
When slighted they will not complain.
And though for them you’ve ceased to care
Your constant friends they’ll still remain.
Good books your faults will never see
Or tell about them round the town.
If you would have their company
You merely have to take them down.
They’ll help you pass the time away,
They’ll counsel give if that you need.
He has true friends for night and day
Who has a few good books to read.
A Study of Reading Habits by Philip Larkin
When getting my nose in a book
Cured most things short of school,
It was worth ruining my eyes
To know I could still keep cool,
And deal out the old right hook
To dirty dogs twice my size.
Later, with inch-thick specs,
Evil was just my lark:
Me and my cloak and fangs
Had ripping times in the dark.
The women I clubbed with sex!
I broke them up like meringues.
Don’t read much now: the dude
Who lets the girl down before
The hero arrives, the chap
Who’s yellow and keeps the store
Seem far too familiar. Get stewed:
Books are a load of crap.
Bottom Line
I just wish to reiterate, with all these best of lists, that these are completely nonexhaustive.
There are dozens of great pieces about books, and even more about reading. I hope you enjoyed the few poems included there! Thanks for reading.
