In 2013 we had a major revision of all four year plans. At that time Poetics only pertained to Year 1, so we decided to remove Poetics and Frameworks from the Loom of all year-plans and make it into one large book we call Poetics. The book is a one time purchase and now covers all four year plans. If you have a year-plan that still includes Poetics and Frameworks on the Loom then by all means you can still use this. If you purchase a year plan with the copyright date of 2013 or newer you will need the new Poetics to complement your year plan if your student is working through rhetoric literature.
*An important reminder: Poetics will not work for year plans older than 2013.
