A crucial work in folklore.
Unfortunately, though, I can't recommend this Barnes & Noble Collectible Edition, as it's missing eight stories, namely:

"Little Red Riding Hood"
"Sleeping Beauty"
"Rumpelstiltskin"
"The Goose Girl"
"The Brave Little Tailor"
"A Voyage to Lilliput"
"Trusty John"
"Little Thumb"

Worse still, it's missing Lang's preface which provides information on sources and translations.
