The library is cloud storage for all the listings you create. One of the great benefits of inkFrog is that we store your listings for you! Even old one's if you so choose. You can use these to build others and/or as a reference for new listings. All live, unsold, sold listings have an attached library or cloud listing. Updating your library (cloud) listing will also update the attached listing on eBay whether it's live, unsold, or sold.
