The hardback edition of The Riverside Chaucer (1987) costs more than $60 (US) and weighs about eight pounds. Fortunately, there is a paperback edition that weighs less than two pounds. Amazon, for instance, sells the book at a 20% discount, for a little under $13. If you add on the cost of shipping, this comes to about $20 (US), depending where you live and on the day you order. To be sure, the paperback is not as durable as the hardback, and it’s printed on cheaper paper; the type is also reduced to fit on a smaller page. On the other hand, you do get all the notes and commentary, and you won’t break your back lugging the thing back and forth to class.
