This edition is the same edition that was published in 1985. It is, of course, the authoritative edition of Chaucer, an essential for any serious Chaucer scholar. As the glosses are insufficient for non-experts, beginning students would do much better with readerly editions such as Cowley's edition of The Canterbury Tales or Kolve's selected volume of The Canterbury Tales and/or Lynch's Dream Visions volume. It is unfortunate that, with the exception of a new foreword, this volume is no different than the 1985 edition: though certain elements are as solid as they will ever need to be, other elements, such as the bibliographic introductions to the individual works are now well outdated. I agree with the earlier review here that the hardcover is well worth the investment: I have worked my 1985 volume hard for the past twenty-seven years, and it is in better condition than my 2008 paperback copy of the Riverside.
