As with all of the Penguin Classics, this is a nicely presented book. An introduction at the start covers the life and works of Chaucer in good detail.
The text has been updated into modern English by Neville Coghill. It is easy to read and retains the effect of Chaucer's poetic language.
The modern English means that it is easy to understand but is not suitable for those needing to study the original English. There are, however, boooks with the original old English.
A very informative set of notes and annotations add to the efectiveness of the translation, and give essential detail needed to understand the text.
All of the tales are included, including the General Prologue.
Worth buying if you need to study the tales or are interested in reading them and understanding them properly.
