This is a massive handsomely produced book of Sw. Vivekananda's most important written works. It includes the books Bhakti and Karma Yoga, Jnana Yoga, Raja Yoga, Inspired Talks, and selected lectures, poems, and letters.

You can also buy The Complete Works of Swami Vivekananda, subsidized edition for $38.00 but the paper and binding are not the same quality as this book, and the material is scattered around eight volumes.
