Term Description Charts

aac

Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme for digital audio. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates.

aacr2

AACR2 stands for the Anglo-American Cataloguing Rules, Second Edition. It is published jointly by the American Library Association, the Canadian Library Association, and the Chartered Institute of Library and Information Professionals in the UK. The editor is Michael Gorman, a British-born librarian living in the Chicago area and honored by both the ALA and CILIP. AACR2 is designed for use in the construction of catalogues and other lists in general libraries of all sizes. The rules cover the description of, and the provision of access points for, all library materials commonly collected at the present time. Despite the claim to be 'Anglo-American', the first edition of AACR was published in 1967 in somewhat distinct North American and British texts. The second edition of 1978 unified the two sets of rules (adopting the British spelling 'cataloguing') and brought them in line with the International Standard Bibliographic Description. Libraries wishing to migrate from the previous North American text were obliged to implement 'desuperimposition', a substantial change in the form of headings for corporate bodies. As well as occasional minor amendments, a broader revision was completed in July 2010 in which the rules are more consistent and coherent, informed by the Functional Requirements for Bibliographic Records. This new cataloging code has been released as Resource Description and Access and is currently undergoing testing at a number of universities as well as the Library of Congress.

accessibility

Accessibility is a general term used to describe the degree to which a product, device, service, or environment is available to as many people as possible. Accessibility can be viewed as the "ability to access" and possible benefit of some system or entity. Accessibility is often used to focus on people with disabilities or special needs and their right of access to entities, often through use of assistive technology. Accessibility is often abbreviated to the numeronym a11y, where the number 11 refers to the number of letters omitted. This parallels the abbreviations of internationalization and localization as i18n and l10n respectively.

ajax

Ajax (shorthand for asynchronous JavaScript and XML) is a group of interrelated web development methods used on the client-side to create interactive web applications. With Ajax, web applications can retrieve data from the server asynchronously in the background without interfering with the display and behavior of the existing page. Data is usually retrieved using the XMLHttpRequest object. Despite the name, the use of XML is not needed, and the requests need not be asynchronous.
