- Abstract
- Discusses articles in which indexing of image collections receives virtually no mention and continues with comments about articles in which indexing receives special attention. Describes four major indexing systems: Library of Congress, AAT, ICONCLASS and TELCLASS. Discusses new indexing approaches where the use of descriptive words is being replaced by other methods of retrieval. Describes indexing by content (attempting to match an input image to a database collection) and by using a visual thesaurus. Raises questions about indexing for various kinds of collections and discusses indexing philosophy

- Abstract
- Explains how computers encode images covering resolution, storage capacity and screen fill rate. Describes image processing by Photoshop software, content recognition and Kodak Photo-CD. Discusses major image indexing projects covering those of the Library of Congress, the Art and Architecture Thesaurus, the BBC's TELCLASS and the ICONCLASS thesaurus based systems. Technology is likely to develop faster than indexing techniques

- Abstract
- The entries, in alphabetical order, cover people, organizations, and technology, including terms and their concepts as having become known up to April 1993. The dictionary contains very short and very long entries, some of them are repeated in different combinations, such as 'Artificial intelligence (AI)' which is combines in separate entries with - expert systems - history - inference - information retrieval applications - knowledge bases - natural language - shells and chaining - software and hardware trends - vision systems. There is no entry for 'index', however many for 'indexing' (7 columns for the concept as such) and combinations, such as Indexing - automatic, - coordinate indexing, - online systems, - system performance, exhaustivity and specifity, - system performance, recall and prescision, - thesauri. Some 5.000 terms, including abbreviations are related to their concepts and are explained and described

- Abstract
- Reviews current image storing and retrieval technology. Describes how images are acquired and the necessary hardware requirements. Examines resolution and storage required for images. Describes compression and imaging applications and examines indexing and retrieval options including use of thesauri, picture description languages, visual thesauri and related ideas, inputting an image and matching against the contents of the database. Gives examples of systems in use. Discusses future developments

- Abstract
- Discusses some aspects of the management of image collections in electronic form. Looks at developments in the UK higher education sector and acquisitions of large picture collections by commercial interests. Considers the indexing and retrieval problems posed by images, particularly in the art field, where a picture may contain hundreds of objects that could conceivably be referenced, and possible solutions being examined, such as the computer matching of shapes
