A set of the Dover paperback reprint edition of 1965 is now being offered at the ridiculous price of $500 on www.bibliofind.com. I have an earlier reprint by Cooper Square, hardbound in 3 vols. There appears to be no reprint currently available.

More reasonable is the single volume edition by G. L Kittredge and Child's daughter, Helen Child Sargent (1904), and thats available 2nd hand at a more reasonable price at the site noted above.
