  Curated web archive collections contain focused digital contents which are
collected by archiving organizations to provide a representative sample
covering specific topics and events to preserve them for future exploration and
analysis. In this paper, we discuss how to best support collaborative
construction and exploration of these collections through the ArchiveWeb
system. ArchiveWeb has been developed using an iterative evaluation-driven
design-based research approach, with considerable user feedback at all stages.
This paper describes the functionalities of our current prototype for
searching, constructing, exploring and discussing web archive collections, as
well as feedback on this prototype from seven archiving organizations, and our
plans for improving the next release of the system.
