Back in 2009 Ted Tjaden put together what I consider a seminal paper called «The 7 Faces of Legal Knowledge Management.» (slaw.ca)
who has recently turned to information management: «Knowledge Management» by Sue Doe, and «The Role of Taxonomies in Legal Knowledge Management Systems» by Christine Miskin. (slaw.ca)
There is an interesting chapter in the BIALL Handbook of Legal Information Management (just released): The Role of Taxonomies in Legal Knowledge Management Systems, by Christine Miskin (213 - 228). (slaw.ca)
