EMC eBooks codes may be used with different students for each year access is purchased. That means the access codes need to be reallocated. Instructors will deactivate the access codes at the end of the school year or the beginning of the next school year. When you deactivate access codes, you must generate new codes.
Log in to the EMC eBooks website at https://emc.bookshelf.emcp.com/ and click Admin on the bottom-right of the page. If you don't have that option, contact your District Administrator for EMC eBooks or Customer Support.
If you are a District or School Administrator, you will be managing multiple teachers. From the Admin page, click Manage Teachers.
This will bring you to a page listing all the teachers in your district or school.
Note: If you are a teacher with Admin access, click Manage Licenses and skip ahead to the Teacher License section.
Determine which teacher’s licenses to view and on the right-hand side of the page, click Action, then click Teacher Licenses.
