A Century of Greek Poetry 1900-2000 Bilingual Edition

There are certainly noted poets from the beginning of the independent Greek nation. I would not try to name the most famous, but two names that repeatedly come up are:
Dionysios Solomos (1798 - 1857)
Kostis Palamas (1859 - 1943)
I will expand on them at a later date.
Constantine P. Cavafy (1863 - 1933)
Author of "Ithaka" and "Waiting for the Barbarians."
Long-time resident of Alexandria, Egypt.
George Seferis (1900-1971)
Nobel laureate, 1963.
I have no clue who is noted or most talked about among contemporary Greek poets, but here is one poet I admire.
Beside my other books, invisible,
existent nontheless, is a volume of silence.
Contained in it are all the things
I hid from view and all that failed
to make the long journey within
me and emerge into the light.
This book is focused on the internet/blog generation of poets and those circulated in 'minor' journals. Many poets, with introduction to their life and work.
Both this book and the collection described in the right-hand column contain a fair number of female poets.
