The list of Personal Information Management (PIM) research prototypes

This list was put together for research purposes.
A review paper about it was published in the Interacting with Computers:
Transference of PIM Research Prototype Concepts to the Mainstream: Successes or Failures.

The list is still being updated. I would appreciate any suggestions of PIM research prototypes that are not listed here.
