Digital preservation refers to the management of digital information over time. Unlike the preservation of paper or microfilm, the preservation of digital information demands ongoing attention. This constant input of effort, time, and money to handle rapid technological and organisational advance is considered the main stumbling block for preserving digital information beyond a couple of years. Indeed, while we are still able to read our written heritage from several thousand years ago, the digital information created merely a decade ago is in serious danger of being lost.
Digital preservation can therefore be seen as the set of processes and activities that ensure continued access to information and all kinds of records, scientific and cultural heritage existing in digital formats.
(April 28, 1898-April 5, 2003) was a major cataloging
theorist and a prominent librarian. Born in Belarus
as Shmaryahu Lubetzky
, he worked for years at the Library of Congress
. He worked as a teacher before he immigrated to the United States in 1927
. He earned his BA from UCLA
in 1931, and his MA from UC Berkeley
. Lubetzky also taught at the UCLA Graduate School of Education and Information Studies
, then the School of Library Service.
Fluent in six languages, Lubetzky published three groundbreaking books that greatly advanced the discipline of cataloging, the organization of knowledge, and modern research methods, still influential in areas of information technology. Cataloging Rules and Principles and Principles of Cataloging, as well as several periodical articles, solidified Lubetzky as one of the most significant influences in his field.
His unfinished book, Code of Cataloging Rules... unfinished draft (1960), was the basis for modern cataloging adopted by the first International Conference on Cataloging Principles (1961) held in Paris, France, called the "Paris Principles." The code which eventually emerged from the conference was a landmark in the history of universal bibliographic control. In 1967 it developed into the Anglo-American Cataloging Rules, which subsequently has been revised over the years.
