Unfortunately, software-component libraries shared on a global scale contain bugs. Members of the library user community often report bugs, workarounds, and fixes. This bug knowledge, however, generally remain undiscovered on library web site or in open bug databases. In this article I describe design criteria for bug handing from a global user community perspective. I also describe a distribution architecture for bug knowledge. The architecture focuses on bug awareness and bug visibility in the standard work environment. © 2005 Elsevier B.V. All rights reserved.
