When you purchase a black line master workbook for use in your classroom, make sure you know exactly what copyrights you are allowed. Some may have a limit to the number of copies allowed or even a time period. Almost all workbooks allow only the purchaser to make copies for his or her classroom, meaning each teacher must purchase their own workbook in order to be able to use them in his or her classroom. At times a publisher may allow an extended group or school copyright to be purchased. If you have a habit of cutting the binding and removing individual pages from purchased workbooks to make copies, be sure you keep the copyright page that details what you are allowed to copy, just in case you need to answer a copyright complaint at some future time.
