With Lightning Source Print On Demand (POD) print and manufacturing technology, there are some formats or bindings that are not available, due to the fast print turn around time we have for books sold through the global distribution network Ingram offers.
Spiral Wire or Plastic type Binding or Curly O Wire
CD’s / Audiobooks
IngramSpark does not currently offer CD production for inclusion in physical books we manufacture. Publishers who wish to offer this feature would need to have IngramSpark print the book and once the publisher receives the printed books, would need to apply/include the disc themselves and sell the books on their own. These books with the audio included could not be sold through Ingram's POD global distribution network.
IngramSpark does not offer audiobook creation services at this time. Publishers looking to find audiobook creation services may find reputable companies listed on our “Experts” page: http://www.ingramspark.com/resources/experts
