Whitman's "Leaves of Grass" is a collection of some of the finest American free-verse poetry ever written. Outward from his home on Brooklyn, Whitman soars out over our great nation, painting a sweeping portrait of mid-nineteenth century America and its diverse inhabitants. Whitman covers a panorama of ideas and themes, from lofty, aloof musings on the nature of man, to piercing depictions of the horrors of war. Gems of wisdom hang from Whitman's web of of verse like dew drops - easy to see but hard to grasp. This is a powerful work, and a never-ending source of beauty. Unfortunately for me, I am not a big fan of free verse, making this work harder for me to enjoy than I had hoped.
Which edition do I recommend? That really depends on what you are looking for. If you are just interested in getting a taste of Whitman, I would recommend some of the abridged versions. I don't feel that reading all 700+ pages of Whitman's poetry is necessary for anyone but his biggest fans and students. For a complete version, I found the Modern Library edition acceptable, but nothing spectacular. This work has a multitude of editions, and I would recommend actually holding them in your hand before making a decision on which best suits your needs.
