A more holistic view of the current situation surrounding image access is needed. Much of the research into content representation of images appears not to recognize a number of basic issues underlying the difficulty in achieving satisfactory results in this area. Beyond the lack of institutional support typically seen in collections of printed matter, visual materials have not received the level of intellectual research needed to develop the theoretical bases behind their access. Several basic issues stand out as being critical obstacles to providing access to visual materials, including a lack of agreement concerning types of information needed, a lack of a universally applied schema, a lack of standard vocabularies, subect indexing, or user studies. In order to provide a general overview of the topic of images and content representation, this article will investigate each of these problematic topics individually.
