This plan allows a professional library to order 10 downloadable resources (mix and match) for $500. These resources are restricted to reference use -- they can not be checked out, photocopied or used in a program. They are to be provided for review only. Order this item and we will email you a coupon code which you can use for up to ten times (you must order items one at a time....sorry for the inconvenience but that's the only way the shopping cart knows how to count!). If you want more than ten resources, order this item again and get a second coupon.
