Dylan Thomas - Collected Poems. Edited by Walford Davies and Ralph Maud (London: Phoenix, 2003.)
This is currently the definitive edition of Dylan Thomas' poetry published in his lifetime (it does not include the Notebook Poems, which are available separately), and contains all the poems from his published collections, plus those later poems published in America as In Country Sleep and Other Poems.
There is a comprehensive notes section at the back of the book.
I see the boys of summer
Where once the twilight locks
A process in the weather of the heart
Before I knocked
The force that through the green fuse
My hero bares his nerves
Where once the waters of your face
If I were tickled by the rub of love
Our eunuch dreams
Especially when the October wind
When, like a running grave
From love's first fever
In the beginning
Light breaks where no sun shines
I fellowed sleep
I dreamed my genesis
My world is pyramid
All all and all
I, in my intricate image
This bread I break
Incarnate devil
Today, this insect
The seed-at-zero
Shall gods be said
Here in this spring
Do you not father me
Out of the sighs
Hold hard, these ancient minutes
Was there a time
Now
Why east wind chills
A grief ago
How soon the servant sun
Ears in the turrets hear
Foster the light
The hand that signed the paper
Should lanterns shine
I have longed to move away
Find meat on bones
Grief thief of time
And death shall have no dominion
Then was my neophyte
Altarwise by owl-light
Because the pleasure-bird whistles
I make this in a warring absence
When all my five and country senses
We lying by seasand
It is the sinners' dust-tongued bell
O make me a mask
The spire cranes
After the funeral
Once it was the colour of saying
Not from this anger
How shall my animal
The tombstone told
On no work of words
A saint about to fall
If my head hurt a hair's foot
Twenty-four years
The conversation of prayers
A Refusal to Mourn the Death, by Fire, of a Child in London
Poem in October
This side of the truth
To Others than You
Love in the Asylum
Unluckily for a death
The hunchback in the park
Into her lying down head
Paper and sticks
Deaths and Entrances
A Winter's Tale
On a Wedding Anniversary
There was a saviour
On the Marriage of a Virgin
In my craft or sullen art
Ceremony After a Fire Raid
Once below a time
When I woke
Among those Killed in the Dawn Raid was a Man Aged a Hundred
Lie still, sleep becalmed
Vision and Prayer
Ballad of the Long-legged Bait
Holy Spring
Fern Hill
In Country Sleep
Over Sir John's hill
Poem on his Birthday
Do not go gentle into that good night
Lament
In the White Giant's Thigh
In Country Heaven
Elegy
