Why does my book have more than one cover on the yearbook ladder?

A single yearbook can contain multiple cover types (Hardcover, Softcover Saddle Stitch, and/or Softcover Perfect bound). This provides the ability to offer the book in multiple styles, at different price points. Cover types should be configured appropriately for each school when the book is originally created, and can only be changed by an Admin. If you need any changes to your available cover type(s) please contact your yearbook provider.

You can copy your cover design from one cover to another. Note: cover types have different spline and margin options, so you may need to adjust design to fit cover format.
