Abstract
Rich image repositories and digital libraries exist for the collection, labeling, archival and delivery of digital graphics. Understanding the ingestion of such images into digital repositories will be helpful not only for those searching for resources but also for those creating digital imagery for such storage and distribution. This chapter addresses some of the latest research going on currently for the labeling of digital graphics, their storage, their protection, and their distribution to users.

TopImage Repositories And Digital Libraries
A digital image repository is a storehouse for various types of contents, without curatorial oversight. A digital image library consists of collections of materials based around topic areas and usually curated by an expert in the respective field. All variety of digital imagery may be archived: maps, photos, geospatial resources, 3D objects, aerial images, satellite images, and remotely sensed image captures. The imagery may be photo-realistic or wholly synthetic.
Repositories and digital libraries may be high-prestige and formal, controlled by designated subject matter experts in a field. They may be wholly public and open to any user. In between are those repositories that may capture less formal imagistic information but which still has value through projects or dissertations (Tschimer & Zipf, 2005) or community contributions (Kennedy & Naaman, 2008).
