Yes, the slip copy on West AW is published later on. The slip copy is a thin paper wrapper that is placed over the dust jacket of a book. It is usually used to protect the dust jacket from damage, and it can also be used to provide additional information about the book. Slip copies are often published later on than the dust jacket, as they may not be needed until the book has been on the market for some time.
