  Here we describe two approaches to improve group information management (GIM)
and draw on the results of prior works to implement them in software
prototypes. The first aids browsing and retrieving from large and unfamiliar
collections like shared drives by dynamically reducing and re-organising them.
The second supports the transfer and re-use of collections (e.g. to/by
successors, descendants, or curators) by integrating novel sorting and
annotation features. The prototypes' source code is shared online and
screenshots are presented in the accompanying poster.
