That includes all Linen Wrap with Dust Jacket and Casewrap binding.Important Note: Projects meeting all distribution requirements for Ingram may still be distributed by Ingram, to Amazon’s marketplace.Ingram’s ExclusionsFor some paperback sizes and bindings, Ingram does not offer 60# Cream Paper.Ingram does not accept coloring books, journals, diaries, or books with many blank or lined pages.Global Distribution AvailabilityWhen you publish a project with a valid ISBN and meet all distribution requirements, we send your project’s metadata and files to Amazon and Ingram.
