Of course this is a wonderful edition containing all of Chaucer's works, accompanied by detailed notes and a thorough glossary. However, for those hoping that the annotations will provide you with a full social and historical context, I'd just like to mention that the Riverside Chaucer tends to "send you off" to other academic books about Chaucer or about life in medieval England. I found this very unhelpful, expecting notes to give me certain insight into Chaucer's life and thought as well as historic contexts, but most of the help comes in the form of "For Chaucer's view of women, see [insert title of book and year of publication]" sending you off to very academic books that not everyone has access to. Of course, this is brilliant if you're looking for a list of books to read for your dissertation, but if you're reading Chaucer just out of interest then you will find very few explanations of themes or social contexts. Personally, I prefer the individual Oxford Student Texts, the notes tell you everything you need to know and explain the text wonderfully; sadly though, the OST have only published some of the Canterbury Tales, and of those that have been published there is just a handful.
