Significant advances have recently been made in the area of updates of logic programs, and, more generally, updates of knowledge bases and their applications. Accordingly, the journal Theory and Practice of Logic Programming has planned a special issue on Change in Knowledge Bases, tentatively scheduled to appear at the beginning of 2003.

High-quality papers are sought containing either original research results or offering an insightful synthesis of past work on various aspects of change in knowledge bases.

Revised and enhanced versions of papers published in conference proceedings that have not appeared in archival journals are eligible for submission. Surveys and comparison of state of the art techniques are also solicited.
